Question

How much is the area of the shaded portion in the following figure

Answer 1

Answer:

Area of shaded region = Area of square PQRS - (Area of triangle QRU + Area of triangle TSU + Area of triangle QPT ) = 400 − (100 + 50 + 100) = 400 – 250 = 150 sq. cm. So, the area of the shaded portion = 150 sq. cm.
