Answer:
d =14
Step-by-step explanation:
![1\frac{1}{2} d -9 =12](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%20d%20-9%20%3D12)
![\frac{3}{2} d = 12+ 9](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%20d%20%3D%2012%2B%209)
![\frac{3}{2} d =21](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%20d%20%3D21)
![d = 21 : \frac{3}{2}](https://tex.z-dn.net/?f=d%20%3D%2021%20%3A%20%5Cfrac%7B3%7D%7B2%7D)
![d = 14](https://tex.z-dn.net/?f=d%20%3D%2014)

12/2=6
So u need to find the circumference of the half circle by finding the circumference of the whole circle and dividing by 2 so that gives you 12.565 then u find the perimeter of the rectangle but not the 4th side cause that’s on the inside when u do that u get 10+10+8 which is 28 then add the half circle and I get 40.565 ft but round to nearest hundred so 40.56 ft
