Answer:
AB=28CM
radius of circle with CENTER O=28/2=14 cm
its area=22×14/7=44 sq. cm
AQ=1/4AB=28/4=7 CM
RADIUS OF CIRCLE WITH DIAMETER AQ=7/2cm
its area=(22×7×7) /(7×2×2)
=77/2 sq. cm
BQ=AB-AQ=21 cm
radius of circle with diameter BQ=21/2cm
its area=(22×21×21) /(7×2×2) =693/2 sq cm
thus, area of shaded region=(693+77) /2
=770/2=385 sq cm
