## Reflection: Lesson Planning The Biggest Possible Area - Section 2: Activity

I would be ready with a graph of a perimeter which results in having maximum area dimensions that are not whole numbers. This can well be an extension of the lesson as well. Say the perimeter of the fencing must be 30 feet. Then the maximum area will have dimensions of 7.5 by 7.5. When students graph this, they wil notice that the vertex is not at whole number values. Yet, they can figure it out because of the symmetry involved.

When the coordinates of the vertex are not whole numbers
