figure=1rectangle+2 semicircles
1semicircle=1/2circle
2 (1/2 circles)=1 circle
figure=1 rectangle+1 circle
area of rectangle=legnth times width
area of circle=pir^2
so the width of the rectangle=diameter of the circle
widht=4
diameter=2r
d/2=r
width=d=4
4/2=r=2
area of circle=3.14 times 2^2
are of circle=3.14 times 4
aera of circle=12.56
area of rectangle=11 times 4
area=44
total=add them up
12.56+44=56.56 cm^2
