Q 20 b part with full solution

Answer 1

hi are of a triangle is 1/2*base*altitude=1/2*AB*CD

1/2*5*AB=35cm²

AB=14cm

now AB is daimeter of the semi circle hence are of semi circle is 1/2*π*r^2

=1/2*π*7²

=76.93

now area of shaded reigon is area of semi circle - area of traingle

=76.93-35cm²

=41.93cm²
