you want to build the rectangular dog pen with 20 yards of fencing against your house which is 20 yards wide. which dimensions will give you the most space for your dog?
ok so your house is 20 yards wide, that akes care of one side if you have only 20 yards of fencing then hmm the way to max the space is to make all side equal
20 is for 3 sides 20/3=6.6666666 per side assuming you don't need to fence the house side
the amount of fencing is 6 and 2/3 by 6 and 2/3 by 6 and 2/3 yards
