## First, A Rectangle Definition

Before we can answer questions like how do you find the area of a rectangle or how do you find the perimeter of a rectangle, let’s start with the basicsâ€”a rectangle definition. If someone were to ask you “what is a rectangle,” I bet you could immediately picture the shape and even draw it, but could you explain it in easy to understand terms?

To help you, here are some properties of rectangles:

- A closed figure.
- A figure with four straight sides.
- A figure with 4 right angles (90 degrees), which means all 4 angles are equal to one another.
- A figure where the opposite (parallel) sides are equal in length.

Based on those properties of rectangles, can we now answer what is a rectangle? How about: A closed figure with 4 straight sides, 4 right angles, and with opposite (parallel) sides that are equal in length.

*Wait, is a square a rectangle?*

To answer this, compare the rectangle definition (above) to the square definition. A square is a regular quadrilateral, which means that it has:

- Four equal sides.
- Four equal angles (90 degrees).
- Opposite sides that are parallel.

That means the answer to “are all squares rectangles” is technically yes. In other words, squares are a type of rectangle. Think of it this wayâ€”thumbs are a type of finger, right?

So can a square be a rectangle? Yes. In fact, technically, the answer to “are all squares rectangles” is yes. However, that does not mean that all rectangles are squares. Going back to that whole “thumbs are a type of finger thing,” not all fingers are thumbs.

*Is a rectangle a parallelogram?*

Before we can determine the answer to are all rectangles parallelograms, we have to first know what a parallelogram is. A parallelogram is a quadrilateral in which the opposite sides are parallel. That means if you kept extending those lines, they would never cross or intersect.

Based on that, and referring back to the rectangle definition, we can answer the question is a rectangle a parallelogram with a resounding yes! We know that the opposites sides of a rectangle are parallel, which makes it qualify as a parallelogram.

*Is a rectangle a rhombus?*

Again, in order to determine the answer to is a rectangle a rhombus we need to understand what a rhombus is. A rhombus is a quadrilateral with four equal sides.

So the answer to is a rectangle a rhombus is maybe, it’s possible. A rectangle could be a rhombus, but definitely not always. The rhombus in question would have to have four equal sides and four equal 90 degree angles, which would make it a square. And as we’ve already discussed in the section “Wait, is a square a rectangle,” a square is a type of rectangle.

Whew! That was a lot of shape definitionsâ€”rectangles, squares, parallelograms, and rhombuses! Who knew math and vocabulary could go hand in hand?

Before we dive into the number crunching portion of this post, like how to use the area of rectangle formula or the perimeter of rectangle formula, I’d like to invite you to download the rectangle printable. It may be very useful in demonstrating the math concepts to your child (or yourself) as you work through them!

## How Many Lines of Symmetry Does a Rectangle Have

Before we get to how many lines of symmetry does a rectangle have, let’s define what a “line of symmetry is.” (Noticing a theme here? ðŸ˜‰ )

A line of symmetry is a line that cuts a shape perfectly in half, meaning that if you were to fold the shape along that line both halves would match exactly.

So the answer to how many lines of symmetry does a rectangle have is 2 because there are 2 ways you could fold a rectangle perfectly in half.

## How to Find the Perimeter of a Rectangle

Feel yourself slipping into an anxiety ridden memory of your high school geometry class? Take a deep breath! We’re going to start with something easyâ€”the perimeter of rectangle formula.

What is the perimeter of a rectangle? Well, when we talk about perimeter, we’re just talking about the length of the outline of a shape. So when you’re asked what is the perimeter of a rectangle, what you’re being asked for is what is the measurement of the outline of the rectangle.

So how do you find the perimeter of a rectangle? You simply add up the length of all four sides. There are a few different ways the perimeter of rectangle formula can be written, but to keep it simple, use:

Perimeter = (2 * L) + (2 * W)

Tip: When figuring out what is the perimeter of a rectangle, don’t forget your order of operations! When solving math problems you want to do things in this order:

- Parentheses
- Exponents
- Multiplication or Division
- Addition or Subtraction

So in how to find the perimeter of a rectangle, you’re going to do things in this order:

- Multiply the length of rectangle by 2.
- Multiply the width of rectangle by 2.
- Add those two numbers together.

## How to Find the Area of Rectangles

What is the area of a rectangle? Well, when we talk about area, we’re talking about the total space an object (like a rectangle) is taking up. So, the perimeter is the outside measurement and the area is the total inside space being occupied. If you’re looking at the colored rectangle shape printable, the part that is colored in is the area.

The good news is that you do not need an area of rectangle calculator to find the area. Okay, maybe if you were dealing with a really large rectangle or decimal points you would want an area of rectangle calculator, but I think you’ll be able to figure out what is the area of a rectangle by hand. I believe in you! ðŸ˜‰

Finding the area of rectangles is not as hard as some other shapes (like **octagon shapes**, for example). So this is a great place to start if you suspect your geometry skills are a little rusty.

For how do you find the area of a rectangle, you will need to know the length and width of a rectangle. If you have those two pieces of information, just deploy the area of rectangle formula:

Area = Length * Width

Yep, that’s it, the area of rectangle formula is just multiplying two numbers together!

*But how do you find the area of a rectangle if you aren’t given the length and width of a rectangle?*

Don’t worry, I can show you how to find the area of a rectangle even if some information is missing. The good news is that no one should be giving you a totally blank rectangle shape and saying “what is the area of a rectangle?” Take a look at what information you have. What if you have the perimeter and the measurement of the width?

Let’s say the perimeter is 100 inches and the width is 20 inches. We can undo the perimeter of rectangle formula to find the length, and then we can calculate the area! Here’s how to find the length of a rectangle, in this situation.

Remember, the formula for the perimeter is *Perimeter = (2 * length) + (2 * width)*, so our formula would look like this:

100 = (2 * length) + (2 * 20)

100 = (2L) + 40

60 = 2L

30 = L

That means the length of your rectangle is 30 inches and the width is 20 inches. You can now calculate the area by multiplying the two together! This example showed you how to find the length of a rectangle, but it would work just the same way for how to find the width of a rectangle.

Again, restating for emphasis, how to find the width of a rectangle is the exact same process!

*What is the surface area of a rectangle?*

When we talk about the surface area of a shape, generally we’re referring to a three dimensional object vs. a two dimensional figure. Therefore, the question would not be “what is the surface area of a rectangle” but rather “what is the surface area of a rectangular prism.”

Now, technically, you could find the surface area of a rectangle since surface area just refers to a measure of the total area that the surface of the object occupies. In the case of a two dimensional rectangle, surface area would just be the area. (Remember, area = length * width.)

## How to Find the Volume of a Rectangle

Technically, the answer to how to find the volume of a rectangle is that you can’t. That’s because rectangles are two dimensional figures and the concept of volume applies to three dimensional objects. Volume is a measure of the amount of space in an object.

So rather than a volume of rectangle formula, you’ll be looking for a volume of rectangular prism formula which is:

Volume = length * width * height

So, remember, if someone asks you for the volume of rectangle formula, what they really need is a the formula for finding the volume of a rectangular prism!
