Answer:
Diameter= 28 cm
Radius = 28/2
= 14
Length of the rectangle= 40 cm
Breadth of the rectangle= 28 cm
Area of the shaded region:
Area of rectangle - 2× Area of semicircles
= l×b - 2pie r²/ 2
= 40× 28 - 22/7 × 14 × 14
= 1120 - 616
= 504cm²
Perimeter of the shaded region:
2( l+b ) - 2(2pie r/2)
= 2(40+ 28) - 2(2× 22/7 × 14)
= 2(68) - 88
= 136- 88
= 48cm
Hope it helped :)
