As shown in the figure, two rectangles A and B are overlapped together. The area of the overlapped part is one third of a and one fifth of B. the known area of B is 60 square centimeters. Find the area of A

As shown in the figure, two rectangles A and B are overlapped together. The area of the overlapped part is one third of a and one fifth of B. the known area of B is 60 square centimeters. Find the area of A

Overlap area = 60 × 1 / 5 = 12 (cm2)
Area of a = 12 △ 1 / 3 = 36 (square centimeter)
