My geometry is rusty. But is the circumference of a circle less that the
rectalinera permieter of the same area? So cost for liner amount of fence
would be less.

Isn't the square size useful as its easier to fence a square than a circle?

Actually, they weren't. But it has been pointed out to me that knowing the
size of a square with the same area is of little use, so with a bit of
formula tidying and an indication of maximum offset instead, here's yet
another.
