A farmer needs to enclose three sides of a meadow with a fence (the fourth side is a river). The farmer has 50 meters of fence and wants the meadow to have an area of 300 sq-meters. What should the dimensions of the meadow be? (For the purpose of this problem, the width will be the smaller dimension (needing two sides); the length with be the longer dimension (needing one side). Additionally, the length should be as long as possible.)
