The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
Substituting the given values into the formula, we have:
60 = 2(18) + 2w
Simplifying, we get:
60 = 36 + 2w
Subtracting 36 from both sides, we have:
24 = 2w
Dividing both sides by 2, we get:
12 = w
Therefore, the width of the rectangle is 12ft.
Solve for each of the formulas for the indicated variable:
If the perimeter of a rectangle is 60ft and its length is 18ft, find its width. (see formula in number 1)
