There are two semicircles in the figure.
Side of the square = 14 cm
Diameter of the semicircle = 14 cm
∴ Radius of the semicircle = 7 cm
Area of the square =14×14=196 cm2
Area of the semicircle =(πR2)2
=(227×7×7)2cm2=77 cm2
Area of two semicircles
=2×154 cm2=154 cm2
Area of the shaded region
= Area of the square - Area of the semicircles
=196 cm2−154 cm2=42 cm2
