proceed with your description and you will find the park is 100 meters on a side, as a square region. This is a very common exercise question.

Let x be the side of one dimension and y be the side of the other dimension. xy=the area, and 2x+2y=400.

, for area.
, simplified perimeter.
You want A as a formula with just a single variable; A as a function of the one variable.
