Answer 1

The measure of a long side is x feet. The measure of a short side is x-8 feet.

Then the length of the fence is equal to 2*x+2*(x-8) = 4x-16.

The second half of conditions (say be a square with a side length to feel less than the length of side a) is not clearly described, its solution cannot be provided.
