23.6.3 The Largest-Area Problem

Core idea

With a fixed length of fence, write the enclosed area as a quadratic in the side length and find the vertex to get the most area.

Module goal. Use the vertex to find the maximum or minimum, and translate everyday optimization problems into a quadratic model.
