Question 1188274
A gardener wants to enclose a garden using 80 concrete curbstones. Each 1m long. 
A) how should the gardener lay out the curbstones to maximize the total enclosed area?
--------------------
Max area for a given perimeter is a circle.
Max area using these pieces is an 80-gon.  A regular polygon with 80 sides.
================================
B) how should the gardener lay out the curbs tone to maximize the total enclosed area is the house is being used as one side?
---
I suspect it's a half-circle.  I'll work on that later.
-------------------------------------
C) how should the gardener lay out the curb stones to maximize the total enclosed area udon ?????? he wants to include a path of the curbstones down the  middle of the garden?

bb tomorrow.  B and C are interesting problems, IMO.
