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.
Given that the perimeter is 60ft and the length is 18ft, we can substitute these values into the formula and solve for the width.
60 = 2(18) + 2W
60 = 36 + 2W
2W = 60 - 36
2W = 24
W = 24/2
W = 12
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)
