D 560 square feet
To find the area of the deck, we need to subtract the area of the pool from the area of the rectangle.
The area of the rectangle is the length multiplied by the width:
Area of rectangle = 40 ft * 18 ft = 720 square feet
The area of the deck is the area of the rectangle minus the area of the pool:
Area of deck = Area of rectangle - Area of pool = 720 square feet - 320 square feet = 400 square feet
Therefore, the area of the deck itself is 400 square feet. So the answer is B) 400 square feet.
wrong
I apologize for the mistake.
Given that the length of the pool is 40 ft and the width is 18 ft, the area of the pool is 40 ft * 18 ft = 720 square feet. However, it is given that the pool itself is 320 square feet.
To find the area of the deck, we need to subtract the area of the pool from the area of the rectangle.
Area of deck = Area of rectangle - Area of pool
Area of deck = 40 ft * 18 ft - 320 square feet
Area of deck = 720 square feet - 320 square feet
Area of deck = 400 square feet
Therefore, the correct answer is B) 400 square feet.
are you sure
