To find the area of the composite figure, first find the area of the rectangle.
14 * 5 = 70
Then find the area of the circle

I can not see the dimension of the radius so just put the radius in the equation.
Then half the area of the circle for the semicircle.
D=11.25

8/15=6/d
cross multiply
8d=90
d=11.25<span />
