You can put this solution on YOUR website! If the maximum area is 57cm with a fixed perimeter of 7 what is the dimensions??
-------------
57 cm is length or distance, not area.
---
The max area of a rectangle with a perimeter of 7 is a square.
1.75*1.75 = 3.0625 sq cm
----
If 7 is the circumference of a circle:
r = 7/2pi
Area = pi*r^2 = 49/(4pi) sq cm
=~ 3.899 sq cm, the max area
