Question 3 (1 point)

The dimensions of a rectangular swimming pool can be represented as (3x - 8) feet and (8x + 7) feet.
Select one answer that represents the area of the swimming pool

Answer 1

Area of pool = 24x²-43x-56 square feet

Explanation:

Given that:

Dimensions of rectangular swimming pool = 3x - 8 and 8x + 7

Area of the swimming pool can be calculated by multiplying the dimensions.

Area of pool = (3x-8)(8x+7)

Area of pool = 3x(8x+7)-8(8x+7)

Area of pool = 24x²+21x-64x-56

Area of pool = 24x²-43x-56

Hence,

Area of pool = 24x²-43x-56 square feet
