Answer 2

Step-by-step explanation:

Area of rextangle = l*b

= 12*8 = 96 cm2

diameter of semicircle = breadth of rectagle

8 = 8

radius = 8/2 = 4 cm

Area of 2 semicircle = 2* 1/2*22/7* 4*4

= 22/7*16

= 50.28

Area of shaded region = are of rectangle + are o f 2 semicircle

= 96 - 50.28

= 45.72
