Find the perimete

Answer :

To find perimeter of shaded region(P)

Radius of semicircle is r = 7cm

Length (L) of side of square = 14cm

P = length of DPC + length of APB + length of AD + length of BC

[Since, DPC and APB are semicircles and Perimeter of semicircle = πr]

P = πr + πr + 14 + 14

= 2πr + 28

= 44 + 28

= 72 cm

Perimeter of the shaded region is 72cm
