Area of Semicircle=1/2(4.5)^2×22/7
Area of Semicircle=11×20.25/7
Area of Semicircle=
Area of Semicircle=222.75/7cm^2
Area of 2 small Semicircle=2×1/2×22/7×(1.5)^2
Area of 2 small Semicircle=22×2.25/7
Area of 2 small Semicircle=49.5/7cm^2
area of circle=22/7×(4.5/2)^2
area of circle=22/7×20.25/4
area of circle=11/7×20.25/2
area of circle=222.75/14
Area of 2 small Semicircle+area of circle
=49.5/7+222.75/14
=321.75/14
area of shadeed portion=Area of Semicircle - Area of 2 small Semicircle+area of circle
area of shadeed portion=222.75/7 - 321.75/14
area of shadeed portion=123.75/14
now
area of one small Semicircle=1/2×22/7×2.25
area of one small Semicircle=11×2.25/7
area of one small Semicircle=27.75/7cm^2
Area of total shadeed portion=area of shadeed portion+area of one small Semicircle
Area of total shadeed portion=123.75/14 + 27.75/7
Area of total shadeed portion=179.25/14cm^2(Answer)
