Jim is setting up a rectangular dog run in

his backyard. He buys six 3-foot sections
of fencing and a 3-foot wide gate. What
are the dimensions of the dog run with
the greatest area in each situation?
a) Jim uses the yard fence for one side of
the dog run.
b) Jim uses the corner of the yard fence
for two sides of the dog run.

The largest area is always a square.

18 feet plus the 3 foot gate = 21 feet. He needs that evenly divided for 3 sides so I would 7 feet on each side. However, the problem is that they come in 3 foot sections. So you have to work this out so that you get as close to a square as possible.
