90 acres=0.141 square miles and I am sorry, but I do not know how many miles not squared are in 90 acres.
90 acres = 0.141 square miles.
Answer: 90 acres = 0.140625 mi²
a sq mile contains 360 acres, so a quarter mile by a quarter mile would contain 90 acres.
There are no miles in any acres, and no acres in any miles.1 square mile = 640 acres
90 * 140 acres = 50,990 390.9 m2
Acres are area. Miles are length.
There is 0.234375 miles in 150 acres
if you mean square acres to square miles there are 12800 acres
