This Strings and Areas assessment also includes:

You'd be surprised what you can do with a string! The constraint is the length of string, and the task is to maximize area. Given a series of composite shapes, learners must create a formula for the maximum area for a specified perimeter. The shapes involve a combination of circles, rectangles, and triangles resulting in some unique configurations.
