Answer:

2644.415 feet spuared

Step-by-step explanation:

I think the attached photo is your full question, and my answer:

We need to find:

- the area of the  pool = π[tex]r^{2}[/tex] = 3.14* [tex]20.5^{2}[/tex] = 1319.585 feet spuared.

- The area of the triangular fence = 1/2* 84*92 = 3964 feet spuared

So, the area of the backyard which is not covered by the pool is:

The area of the triangular fence - the area of the  pool

= 3964 - 1319.585

= 2644.415

Hope it will find you well.
