Answer:
area= 604 cm^2
perimeter=376 cm
Step-by-step explanation:
radius(r)=28/2
=14 cm
<em>area of the semicircle</em>=2r*theta /360
=2*22/7*14*180/360
=44cm^2
<em>area of the rectangle</em>=l*b
=28*20
=560 cm^2
<em>total area</em>=semicircle area+rectangle area
=560+44
=<u>604 cm^2</u>
<em>arc length</em>=*theta/360
=22/7*14*14*180/360
=308cm^2
<em>perimeter</em>=28+20+308+20
=<u>376 cm</u>
