Answer :

It can be observed from the figure that the radius of each semi-circle is 7 cm

Area of each semi-circle =r2


= * * (7)2


= 77 cm2


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
