Question

The length of a rectangle is 1 less than twice the width. The area of the rectangle is 28 square feet. Which equation represents the situation?

Answer 1

2w^2 - w - 28 = 0, I dont know how this is right but it is 

Answer 2

2W²-W-28 = 0 is the equation.

Explanation:

To form the equation we should always follow the statement as said.

First statement is

The length (L) of a rectangle is 1 less than twice of width (W).

Means L = 2W - 1 -------(1)

Second statement

Area of the rectangle is 28 feet²

Means L×W = 28 ------(2)

Now by putting the value of L from equation 1 to equation 2.

(2W - 1)×W = 28

2W² - W = 28

2W² - W - 28 = 0

This the equation that represents the situation.
