Answer 1

ANS: 98.175 sq. cm

Area of semicircle with center at B=

(πr^2)/2=(π*5*5)/2=12.5π cm

Area of semicircle with center at C=

(πr^2)/2=(π*5*5)/2=12.5π cm

Area of the quadrant with center at D=

(πr^2)/4=(π*5*5)/4=6.25π cm

So,Total area of the figure=(12.5+12.5+6.25)π

=31.25π

=98.175 sq.cm
