How many acres is 70 by 70 feet?

Answer 1

An acre contains 4840 sq yards, or 43560 sq. feet.

A 70 x 70 ft. plot is 70*70 sq feet, or 4900 sq feet.

4900 / 43560 =~ .112 or 11.2% of an acre.

1/8 acres would be 12.5%, and 7/64 would be 10.9% so there's no standard fraction that satisfies this problem.
