Day 4 - Cagey Problem Part 2

Today we did a short optimization activity that followed directly from yesterday's work. We optimized a rectangle with a fixed area:

Again, this activity took students at most half an hour. They completed it easily but it was a little harder than yesterday's work. Once they got how it worked, they filled out the table well enough. We noticed that while we got a perfect parabola yesterday, today the graph did not look that way:

We discussed briefly why it did not give us a perfect parabola, but students were keen to get back to their floor plans.
