Problem
A rectangular field is to be constructed alongside a straight river so that no fencing is required on the side bordering the river. If 120 m of fencing is available for the remaining three sides, determine the dimensions (length parallel to the river and width perpendicular to the river) that maximize the enclosed area. State both dimensions in meters.
