A) A square has an area of 121 cm^2. What is the length of each side?

b) A square has a perimeter of 28m. What is the length of each side?

A square has equal sides. To find the area, you multiply the length and the height.

x*x=121

x^2=121

x=11

The length of each side is 11

A square has equal sides. To find the perimeter, you add all the sides together.

x+x+x+x=28

4x=28

x=7

The length of each side is 7
