To find the width of the rectangular rug, we can use the formula for the perimeter of a rectangle:
\[
P = 2 \times (L + W)
\]
where \( P \) is the perimeter, \( L \) is the length, and \( W \) is the width. We know the perimeter is 40 feet and the length is 12 feet. Plugging in the values:
\[
40 = 2 \times (12 + W)
\]
Next, divide both sides by 2:
\[
20 = 12 + W
\]
Now, subtract 12 from both sides to solve for \( W \):
\[
W = 20 - 12
\]
\[
W = 8
\]
The width of the rug is 8 feet.
\[
P = 2 \times (L + W)
\]
