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? What is the length of the rectangle?

Answer 1

Answer:

Step-by-step 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.

Answer 2

Answer:

1st answer is B (2w^2-w-28=0)  

2nd answer is 7 feet
