Answer:
Area of Rectangular Deck : 370 square feet
Step-by-step explanation:
To solve this problem we would have to subtract the area of this rectangle that is bordered around the pool, and the pool itself to receive the square feet of wood for the deck;
Area of Rectangular Deck, with Pool ⇒ length * width = 15 feet * 30 feet = 450 feet^2,
Area of Pool ( triangular shape ) ⇒ 1/2 * base * height = 1/2 * 20 feet * 8 feet = 10 feet * 8 feet = 80 feet^2,
Thus, by the Partition Postulate;
Area of Rectangular Deck ⇒ 450 feet^2 - 80 feet^2 = 370 feet^2 ⇒
* Area of Rectangular Deck : 370 feet^2 *
