Let the width of the rectangle be represented as "w" and the length be represented as "2w".
The perimeter of a rectangle is given by the formula:
Perimeter = 2(length + width)
Given that the perimeter is 42 ft:
42 = 2(2w + w)
42 = 2(3w)
42 = 6w
w = 7
Therefore, the width of the rectangle is 7 ft and the length is 2w = 2(7) = 14 ft.
So, the length of the rectangle is 14 ft and the width is 7 ft.
The length of a rectangle is twice its width.
If the perimeter of the rectangle is 42 ft, find its length and width.
