Check the picture below.

so, if the semi-circle has a diameter of 36, then the radius is half that, or 18

\bf \textit{area of a semi-circle}\\\\
A=\cfrac{\pi r^2}{2}\quad 
\begin{cases}
r=radius\\
-----\\
r=18
\end{cases}\implies A=\cfrac{\pi 18^2}{2}\implies A=\cfrac{324\pi }{2}
\\\\\\
A=162\pi

x =7y ----(1)

xy=252 ----(2)

(1) into (2):

(7y)(y) = 252

7 {y}^{2}  = 252 \\ 7y =  \sqrt{252}

7y=15.874....

y=2.27

y value into (1)

x= 7(2.268)

x=15.87
