Area and formulas

Question

The square below has an area of 144   . The perimeter of this square is  in.

Answer 1

If the area is 144, take the square root to determine the length of one side

s=√144 = 12

The perimeter is the length of all 4 sides together. Since all 4 sides are the same,

Perimeter = 4 sides x 12 inches

Perimeter = 48 inches

Answer 2

If a square has an area of 144 in², then the square root of 144 is the side length of that square - 12.

If a square has a side length of 12 in, then the perimeter of that square is 4 x 12 in = 48 in.
