Question

in following figures find the area of shaded regions​

Answer 1

Answer:

Hence radius of the semi-circle (r) = 2cm. Therefore the side of the inner square = 4cm. Now, area of shaded region = area of big whole square – area of small inner square – area of 4 semi-circles. ⟹Area of shaded region = 196 – 16 – 25.12 = 154.88cm2.
