perimeter of a rectangle

Question

a rectangle is 156 square feet and the length of one side is 13 feet. what is the perimeter of the rectangle?

Answer 1

Since the area is 156 then this equals 13 times the length of the adjacent side which equals 12 (dividing 156 by 13). The perimeter is the sum of all 4 sides or 13 + 13 + 12 + 12 = 50
