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 of the rectangle is 60ft and its length is 18ft, we can substitute these values into the formula and solve for the width:
60 = 2(18) + 2w
60 = 36 + 2w
Subtract 36 from both sides:
60 - 36 = 2w
24 = 2w
Divide both sides by 2:
24/2 = w
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)
