**Area and Perimeter Definition**

**Area and Perimeter Definition**

**Area is the amount of space that the inside of an object takes up.**

** Perimeter is the total length (distance) of the outside of an object.**

### Another way of finding the area of a rectangle is using an **array**. An array means using rows and columns then adding it all up. If each row has 18 squares, if we have 6 rows, we would then go 6 x 18 which is 108 squares in total.
