Solving a Geometry Application

[Takitia]

Does this statement apply to the following problem?
If so what am I to do next?

P=2w+2L

The length of a rectangular playing field is 5 ft less than twice its width.
If the perimeter of the playing field is 230ft,find the length and width of the field.

\(\displaystyle \L\begin{array}{l}
2L + 2W = 230 \\
L = 2W - 5 \\
\end{array}\)
