How long is ten acres?

Ten acres can be any length, depending on how wide the area is that you are drawing the boundary around. One acre is 4,840 square yards. So a 10 acre area of land one yard wide would be 40,840 yards, or 27.5 miles long. Not an easy field to plough. On the other hand a 10 acre area of land 100 yards wide would be 484 yards long. One acre, as a square, would be 69.57 yards on each side.
