We are given a square base that has an area of 144 ft2. Let s be the side length. The area of a square of side s is s2 . Thus we have s2 = 144. Since 144 is just 122, then s = 12 ft.
We are asked for the perimeter of the square base. The perimeter of the base of a square with side s is just 4*s, or 4*12 = 48 ft.
