URGENT The area of a rectangular floor is 80 square feet. The length of the floor is 2 feet less than the width of the floor. What is the width of the floor?

Drag the answers into the boxes to correctly complete the statements.

The equation Response area , where w is the width of the floor in feet, can be used to solve this problem. The width of the floor is Response area feet.

The width of the floor is 10 ft.

Step-by-step explanation:

First, you have to form expressions of width and length in terms of w. With the given information :

width = w ft

length = (w - 2) ft

Given that the area of rectange is A = length × width so you have to subtitute the expressions and value into the formula :

A = l × w

80 = (w - 2) × w

w(w - 2) = 80

w² - 2w = 80

w² - 2w - 80 = 0

(w + 8)(w - 10) = 0

w + 8 = 0

w = -8 (rejected)

w - 10 = 0

w = 10
