Given:

The width of rectangle is w = 5x - 4.

The perimeter of rectangle P = 14x + 4.

Step-by-step explanation:

The formula for the perimeter of rectangle is,

Substitute the expression in formula to determine the length of rectangle.

$\begin{gathered} 14x+4=2(L+5x-4) \\ L+5x-4=(14x+4)/(2) \\ L=7x+2-5x+4 \\ =2x+6 \end{gathered}$

So length of rectangle is 2x + 6.

Answer: 2x + 6
