Description discusses lengths and an area.

Dimension for the SQUARE are 2(3x+1) and 2(3x+1).
Area of the square is 2%5E2%2A%283x%2B1%29%5E2.

Let the length of the rectangle be L.
Given is that width of the rectangle is 3x+1.
Area of the rectangle is %283x%2B1%29L.


Also given is that ......
... %283x%2B1%29L=2%5E2%283x%2B1%29%5E2, and the question asked is, what is L.
