The best way to answer is to expect the trinomial to be factorable, which it is.
Area is (2x-1)(x+3). This would suggest that the variable dimensions of the rectangular park are 2x-1 and x+3.

The total length of the fencing needed for this perimeter is:
2%282x-1%29%2B2%28x%2B3%29
4x-2%2B2x%2B6
highlight%286x%2B4%29, the length of fencing needed.
