Answer:

The width of the rug is 8 feet

Step-by-step explanation:

The Perimeter of a Rectangle

Given a rectangle of width W and length L, the perimeter is the sum of all its external side lengths, that is:

P = 2W + 2L

We are given the perimeter of a rectangle rug is P = 40 feet, and the length is L= 12 feet. Substituting:

40 = 2W + 2*12

Dividing by 2:

20 = W + 12

Solving for W:

W = 20 - 12 = 8

The width of the rug is 8 feet
