Find the area of the shaded region in figure, if ABCD is a square of side 7 cm. and APD and BPC are semicircles.
(use π = 22/7)
Area of shaded region = Area of square – area of 2 semicircles
Area of square = 7 × 7 = 49 sq.cm
Area of semicircles = 
= π × r2
= π × 3.52
= 38.5 sq.cm
Area of shaded region = 49-38.5 = 10.5 cm2
