It can be observed from the figure that the radius of each semi-circle is 7 cm.
Area of each semi-circle = 1/2 πr2
= 1/2 x 22/7 x 7 x 7
=77cm2
Area of square ABCD = (Side)2 = (14)2 = 196 cm2
Area of the shaded region
= Area of square ABCD − Area of semi-circle APD − Area of semi-circle BPC
= 196 − 77 − 77 = 196 − 154
= 42 cm2
