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

Area of each semi-circle = 1/2 πr^{2}

= 1/2 x 22/7 x 7 x 7

=77cm^{2}

Area of square ABCD = (Side)^{2} = (14)^{2} = 196 cm^{2}

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 cm^{2}
