Pace Yourself When Doing This Problem

There is a square town of unknown dimensions. There is a gate in the middle of each side. Twenty paces outside the North Gate is a tree. If one leaves the town by the South Gate, walks 14 paces due south, then walks due west for 1775 paces, the tree will just come into view. What are the dimensions of the town.

Solution: One reader (B.S.) suggests: "Is the town 180 paces by 180 paces?" Another person thinks that it is 250 paces by 250 paces.

Do you agree or diasagree with either answer?
