There isn't "one answer".

I wonder who locked this question in search of an answer?
Just as a problem in geometry, the perimeter could be almost
infinitely long if the area was in the form of an extremely narrow
strip, or if the area were a circle, that would allow the shortest
perimeter.
But neither of those extremes will do for a lot.  Assuming that it is
rectangular in shape, you need the length of any one side or the
proportions of length to width.
And you will need to convert acres to square feet.
