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
