A classical problem: Mr. Smith has 20km of fence and wants to delimit a rectangular shaped piece of land. How should he do it in order to maximize the area?

Using TI-Nspire's geometrical and data capture capabilities we solve this problem by analyzing the data and fitting a suitable curve.

This activity includes several questions for the students. After answering them, they can save the document with a new name and transfer it to the teacher's handheld. The teacher can then review their work in his own TI-Nspire.
