Step-by-step explanation:
4(5 + x) = 2x + 2
that is my understanding of the given problem.
if you made a typo, please adapt the following solution.
4×5 + 4×x = 2x + 2
20 + 4x = 2x + 2
20 + 2x = 2
2x = -18
x = -9
Answer:
50 ft.

Let,
Width = 2x ft
Length = 5x ft
Perimeter of the rectangle is
It is given that the perimeter of the rectangle is 140 ft.
