Answer:The width of the rectangle is 5 feet.
Step-by-step explanation:
Let w represent the width of the rectangle.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(W + L)
where W is the width and L is the length.
If the length of the rectangle is 12 feet more than the width, the expression would be
L = W + 12
Suppose that the perimeter of a rectangle is 44 feet, it means that
2(W + L) = 44
Dividing both sides of the equation by 2, it becomes
W + L = 22 - - - - - - - - - - - -1
Substituting L = W + 12 into equation 1, it becomes
W + W + 12 = 22
2W + 12 = 22
2W = 22 - 12 = 10
W = 10/2
W = 5
Answer:
5 feet
Step-by-step explanation:
We are told that L=W+12, and that the perimeter is 44. If we substitute for L in the formula for perimeter and set it equal to 44, we can do a little algebra to solve for W:
2(W+L)=44
2(W+(W+12))=44
4W+24=44
4W=20
W=5
