Which grade is she in? There are two very different ways of solving this :)

Just a rule of thumb. If you want maximum area of a rectangle you should always make it into a square. All sides being equal.
If you have 188ft or fence how much can you use for each side, so that every side has the same length?

188 / 4 = 47
=> Each side is 47 ft:
The area then becomes: 47 * 47 = 2209 ft^2
