a rectangular swimming pool is represented by x as the width and one less than twice the width as the length. if the area of the swimming pool is given by 28 sq. ft., which equation could be used to model the area of the swimming pool?

a) 28 = 2x - 1•x

b) 28x = 2x - 1

c) 28 = (2x - 1) + (x)

d) 28 = (2x - 1)(x)

28=(2x-1)(x)

Step-by-step explanation:

The swimming pool is rectangular in shape.

Hence the area of it is given by:

l * w

where l = length of the rectangular swimming pool

          w = width of the rectangular swimming pool

In this question it is given:

width = w = x

length = l = 2x - 1

Area = 28 sq.ft

Hence:

Area = l * w = (2x-1)(x)

28 = (2x-1)(x)

your answer would be 10x - 1
