Rectangles and Parabolas
Activity Overview
Students will tackle a traditional problem from the Algebra I curriculum geometrically, numerically, graphically, and algebraically:
Sixty feet of fencing is purchased for the grounds crew to fence off a rectangular portion of property for a garden. The owner has made it perfectly clear that he would like the rectangular plot of land with the greatest area. Help the grounds crew decide on the dimensions for the maximum area.
