It could be a square that's 0.71 miles on each side.
At the level asked there is no difference. As the size goes up there is a big difference... Two miles square would be 2x2 = four square miles.
One half mile times one half mile is equal to one quarter square mile.
One square mile is equal to about 2.6 square kilometers.
1 sq mile
There are 320 acres in a half mile by a half mile area.
57,914 square miles.
There are 640 acres in 1 square mile. So (1/2 mile)*(1/4 mile) = 1/8 square mile, or:(1/8 square mile)*(640 acre/square mile) = 80 acres
A half mile is equivalent to 2,640 feet. Therefore, a parcel of land measuring half a mile by half a mile would be 2,640 feet by 2,640 feet. To convert this into acres, we multiply the two dimensions together and then divide by the number of square feet in an acre, which is 43,560. So, (2,640 x 2,640) / 43,560 = 160 acres.
1/8th
A square mile is equal to 640 acres A square kilometers is smaller as a km = 0.6213711922 miles So a square kilometer would be 398 acres
A square mile is an area measurement, not a specific shape. They could be just about anything, as long as they multiply together to make one square mile. 1 mile by 1 mile is a square mile. Two miles by half a mile is a square mile. 1 foot by 5280 miles is a square mile. This means that 8 square miles can be 2 miles by 4 miles or 1 mile by 8 miles.
