## What Is Perimeter? A Kid-Friendly Definition

When we're introducing any concept for the first time, we know that having a kid-friendly definition on hand can be helpful to start the lesson. Here's a perimeter definition that our teacher team likes to use!

Perimeter is the measurement of the distance around the outside of a shape. If you were to walk all the way around an object, the distance you walked would represent the perimeter of that object.

The perimeter of a shape depends on the lengths of its sides.

## How to Find Perimeter of a Shape — A Simple Formula for Students

To find the perimeter of a shape such as a square or triangle, students need to add up the lengths of all its sides.

For example, if you're trying to find the perimeter of a rectangle, you would use the formula:

- Perimeter = Length + Width + Length + Width

If you're trying to find the perimeter of a triangle, the formula is a bit simpler as there are fewer sides! In this case, the formula is:

- Perimeter = Side + Side + Side
