NEED AN ANSWER ASAP

The width of a rectangle is 6 units less than the length. The area of the rectangle is 7 units. What is the width, in units, of the rectangle?

 

Answer:

The width is 1 unit.

Step-by-step explanation:

Length: x

Width: x - 6

Area: 7 sq. units

Equation:

(length) (width) = area

(x) (x-6) = 7

x² - 6x - 7 = 0

Factor the equation:

(x - 7) (x + 1) = 0

Equate each factor to 0:

x - 7 = 0

x = 7

x + 1 = 0

x = - 1

Choose the positive value for dimensions.

Length: x = 7 units

Width: (7)-6 = 1 unit

The width is 1 unit.
