1280 square acres is how many miles?

Answer 1

There is no such unit as the "square acre". The "acre" is a unit of area = 43,560 square feet.

"Mile" is a unit of length or distance, not area. The "square mile" is one possible unit of area.

640 acres = 1 square mile

1,280 acres = (1,280/640) = 2 square miles

Answer 2

1280 square acres is equivalent to 2 square miles.
