Answer:
146.5 sq. feet.
Step-by-step explanation:
Area of the deck = Large Square (with 15 ft side) - Circular Pool (with radius 10/2=5)
Large Square area = ![s^2=(15)^2=225](https://tex.z-dn.net/?f=s%5E2%3D%2815%29%5E2%3D225)
Circular Pool area = ![\pi r^2=\pi (5)^2=\pi (25)\\=25(3.14)\\=78.5](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%3D%5Cpi%20%285%29%5E2%3D%5Cpi%20%2825%29%5C%5C%3D25%283.14%29%5C%5C%3D78.5)
Thus, area of deck surrounding pool =
