Answer:
<em>The width of the rug is 8 feet</em>
Step-by-step explanation:
<u>The Perimeter of a Rectangle</u>
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
