Answer 1

Answer:

115.5 cm²

Step-by-step explanation:

For The semicircle ARC r=7 cm

So A1=πr²/2

=(22/7*(49))/2

A1=22*7/2=77 cm²

For The semicircle BSD r=7 cm

So A2=77 cm²

For The semicircle APB r=7 /2=3.5 cm

A3=πr²/2=22/7 *(3.5)(3.5)/2

=22*3.5*3.5 /14

=11*7*3.5/14

=11*3.5/2

=19.25 cm²

similarly

For The area of semicircle APB=19.25

Thus the shaded area

=A1+A2-A3-A4

=77+77-19.25+19.25

=154-38.5

=115.5 cm²
