He can layout the fence in any closed shape he wishes, and in doing so he will have enclosed a small area (on one side), and the remainder of the surface area of the earth (on the other side). Going to a bigger planet offers more possibilities.

Actually the twisted version will be:

Earths surface area - 0 sq ft. (Why make a big area with the fence wire if you want to substract it from trhe Earth's area? Just put it somewhere on the floor in a ball)
