Question

How do I find a perimeter

Answer 1

The perimeter is the total distance around the sides of a 2 dimensional shape. To calculate a perimeter, add up all the side lengths around the shape

Example:

2 by 5 rectangle

2 of the sides are 2 long

2 of the sides are 5 long

Add up the measures:

2 + 2 + 5 + 5 = 14

perimeter is 14

Answer 2

By adding all of the numbers on the the outside lines
