Answer:

area= 604 cm^2

perimeter=376 cm

Explanation:

radius(r)=28/2

=14 cm

area of the semicircle=2
$\pi$ r*theta /360

=2*22/7*14*180/360

=44cm^2

area of the rectangle=l*b

=28*20

=560 cm^2

total area=semicircle area+rectangle area

=560+44

=604 cm^2

arc length=
$\pi$
r^(2) *theta/360

=22/7*14*14*180/360

=308cm^2

perimeter=28+20+308+20

=376 cm

Hope this helps you.
