Each side is . There are 4 of these sides that are the same length. So we multiply that side length by 4 and set it equal to the perimeter of 28

Let's solve this equation for x

Now we use the fact that x = 3 to find the side length

So each side length of this square is 7 inches. You can simply divide 28 over 4 to see this

28/4 = 7

Your teacher will most likely want you to solve for x first though.
