Using the perimeter given, find the dimensions of the rectangle with the greatest area using the whole units.
1. P=10
2. P=40
3. P-64
-------------
A square has the maximum area of rectangles with a specified perimeter. Do you need a proof of that?
-----------
1. P=10
s = 10/4 = 2.5
Area = s^2 = 6.25 sq units
-------------
2. P=40
s = 10
Area = 100
--------------
3. P=64
s = 16
Area = 256
