 $\begin{array}{r} l = & \sqrt{6 x - 5} \\ w = & 4 \end{array}$

Step 1

The perimeter of a rectangle is equal to the sum of all sides of the rectangle.

$l e n g t h + l e n g t h + w i d t h + w i d t h = 2 \cdot (l e n g t h) + 2 \cdot (w i d t h)$

Step 2

$2 \cdot 2 \cdot 4$

Step 3

Multiply $2 \cdot 2 \cdot 4$ .
