A square would need to be approximately 361.5 feet on each side to contain three acres.
If the three acres is a square then the perimeter would be 1,445.99 feet or 1,445 feet and 11.88 inches.
There would be 152,460 square feet in 3.5 acres. An acre is 43,560 square fee. Simply multiply the 43,560 by 3.5.
A square mile is 640 acres, therefore 36 square miles would equal 23,040 Acres.
227 square miles is 145,280 acres.
15 square miles = 9,600 acres.
93.6 square miles = 59,904 acres.
A foot is a unit of length, an acre is a unit of area. You can't convert that. 1 acre is 198 by 220 feet or 43560 square feet, 4840 square yards and 6272640 square inches. So the answer to your question, how many ft is 3 acres would be 594 by 660 feet or 130680 square feet.
0.17 acres is 7,405.2 square feet.
There are 0.83 acres in 36,000 square feet.
4.8 acres is 209,088 square feet.
the area is 64 square miles, by my conversion that would be 40,960 square acres
A square area that was two acres would be about 295 feet on each side.
