Your question is nonsense as:
However, if you mean how many SQUARE miles are in 31/2 acres:
1 acre = 1/640 sq mi
→ 31/2 acres = 31/2 x 1/640 sq mi
= 7/1280 sq mi
≈ 0.0055 sq mi
There are no miles in any acres, and no acres in any miles.1 square mile = 640 acres
To calculate the area in acres for a rectangle that is 1 mile by 0.5 miles, first convert the dimensions to acres. Since 1 square mile is equal to 640 acres, the area is 1 mile × 0.5 miles = 0.5 square miles. Thus, 0.5 square miles is equal to 0.5 × 640 acres, which equals 320 acres.
1,024,000 acres.
Answer: 1,600 acres = 2.5 square miles.
3.90 square miles = 249,600 acres.
There are 640 acres in a square mile and 1.5 by .5 miles is .75 square miles. Therefore, there are 480 acres in a piece of land 1.5 by .5 miles.
Three square miles = 1,920 acres.
Central Park is 843 acres. It is approximately half a mile wide, and two and a half miles long.
There are approximately 1.24 acres in half a hectare.
There are no miles in any acres, and no acres in any miles.1 square mile = 640 acres
To calculate the area in acres for a rectangle that is 1 mile by 0.5 miles, first convert the dimensions to acres. Since 1 square mile is equal to 640 acres, the area is 1 mile × 0.5 miles = 0.5 square miles. Thus, 0.5 square miles is equal to 0.5 × 640 acres, which equals 320 acres.
90 acres=0.141 square miles and I am sorry, but I do not know how many miles not squared are in 90 acres.
1,024,000 acres.
2,560 Acres.
There is 0.234375 miles in 150 acres
42,000 Acres = 65.625 Square Miles
3 acres is equal to 0.0047 square miles.
