Answer:
Divide Perimeter by 4
Divide the perimeter by 4 to obtain the length of each side, since all four sides of a square are equal. For example, a square with a perimeter of 36 inches would have sides that measure 9 inches each because
36 ÷ 4 = 36÷4=9
Square Length of Side
Square the length of one side. For a square with 9-inch sides, work out
9 × 9 =81
Add Unit of Measurement
Add the proper unit of measure to the area. A square with a perimeter of 36 inches has an area of 81 square inches.
