Question

A rectangular polygon consists of five squares placed side by side. The perimeter of the rectangle is 60 inches. What is the area of the rectangle in square inches?

Answer 1

rectangle = 5 squares side by side

perimeter = 60 inches = 2(L+W)

L+W = 30 inches

L=5W

5W +W = 30

6W =30

W =30/6 = 5 inches

L=5(5) = 25 inches

area = LW = 25(5) = 125 square inches
