Area of rectangle= 21*10.5 =220.5cm^2
Diameter of the smaller semicircle is half the diameter of the larger semicircle.
i.e. why diameter of big semicircle= 21-5.2
=15.8cm
area of small semicircle
=1/2πr^2=0.5*3.14*2.6*2.6=10.6cm^2
area of big semicircle=1/2πr^2 =0.5*3.14*7.9*7.9
=97.9cm^2
Area of non shaded region= 220.5-(10.6+97.9)
=112cm^2
