Multiple Choice

A facilities manager is planning a rectangular break area with an area of 180 square feet, where the width must be 3 feet less than the length ll. The solving process leads to the quadratic equation l2−3l−180=0l^2 - 3l - 180 = 0, which yields two mathematical solutions: l=15l = 15 and l=−12l = -12. According to the geometry problem-solving strategy, why is the solution l=−12l = -12 discarded?
