If 1 acre of land is avalible, and each tree is 25 feet apart, how many trees can you fit in the acre of land?
1 square mile=640 acres
5280^2=640 acres,
1 acre=43,560 square feet
1acre=sqrt(43,560)
1acre=208.7^2 feet on each side
208.7/25=8.35 or 8 trees on one side, therefore,
8 X 8=64 trees, vertically and horizontally
