A swimming pool and deck are built in a rectangle with length 40 ft and width 18 ft. If the pool itself is 320 square feet, what is the area of the deck itself?

A) 320 square feet
B) 400 square feet
C) 480 square feet
D) 560 square feet

I think it is c.

Thank you! 40 x 18= 720 720-320= 400

(40 * 18) - 320

check again

So is it 320 or is it 400?

thanks

To find the area of the deck, we need to subtract the area of the pool from the total area of the rectangle.

The total area of the rectangle is given by the formula: length multiplied by width.

So, the total area of the rectangle = 40 ft * 18 ft = 720 square feet.

Since the pool itself is 320 square feet, we subtract this from the total area to find the area of the deck.

Area of the deck = Total area of rectangle - Area of pool = 720 square feet - 320 square feet = 400 square feet.

So, the area of the deck is 400 square feet.

Therefore, the correct answer is B) 400 square feet.
