This problem challenges students to work systematically while applying their knowledge of areas of rectangles. It offers opportunities for higher level mathematical thinking (optimizing and graphing) in a context that doesn't require sophisticated mathematical content.
This problem could be revisited when students are older and are able to use algebraic techniques (forming quadratic expressions, maximizing by completing the square).
