The perimeter of Jonah's square backyard is 56 meters.

What is the area of Jonah's backyard?

The perimeter is the length of each side added together. Since all sides are the same length on a square, you can just divide by 4:

56m/4=14m

The area of a rectangle is base x height; since the sides are the same length,

A=s*s=14m*14m=196m^2

224 because his backyard is a square and all squares have the same length of sides so there are 4 sides so you multiply 56*4
