Given field, perimeter = 180+240=420 yards. Area = 12600 sq.yds.
Wanted x and y, 2%28x%2By%29=420 and xy%3E12600

Solve the equation either for x or y, and substitute this into the inequality. Solve the resulting inequality. You might want to repeat the method starting with the other variable from the equation.

Any rectangle with sides 90 < w <= 115 and l + w = 230 will have a greater area.
