Answer:
206.9 square feet
Explanation:
We know that the amount of wood purchased has to equal the area of the deck minus the area of the hot tub.
Lets find the area of the hot tub.
[tex]d/2=r\\12/2=6\\\\A=\pi r^{2}\\A=\pi*6^2\\A=36\pi\\[/tex]
Lets make pi equal to 3.141
[tex]A=36*3.141\\A=113.076 ft^2[/tex]
Now lets find the area of the deck.
[tex]A=l*w\\A=20*16\\A=320 ft^2[/tex]
Subtract the area of the hot tub from the deck.
[tex]320-113.076=206.924 ft^2[/tex]
