Thank you in advance!

Answer 1

`289\ ft^(2)`

Explanation:

we know that

To find the area of the backyard that is not covered by the hot tub and fire pit subtract the area of the hot tub and the area of the fire pit from the total area of the square backyard

so

`A=20^(2)-(6)(8)-(7)(9)\\A=400-48-63\\ \\A=289\ ft^(2)`
