The answer is exactly 1 square mile. 160 acres is a quarter mile square. A square mile is 5280 ft X 5280 ft = 27,878,400 sq ft and an acre is equal to 43,560 sq ft or approximately 208.710 ft X 208.710 ft. C Painter

192 ft * 465 ft = 59985 ft² Converting that to acres is: 1.3771 acres Algebraic Steps / Dimensional Analysis59,985 ft²*1 acres 43560 ft²=1.377066116 acres

70 ft x 214 ft = 0.344 acres, approx. 70 ft x 214 ft = 0.344 acres, approx. 70 ft x 214 ft = 0.344 acres, approx. 70 ft x 214 ft = 0.344 acres, approx.

100 ft * 125 ft = 0.287 acres (approx). 100 ft * 125 ft = 0.287 acres (approx). 100 ft * 125 ft = 0.287 acres (approx). 100 ft * 125 ft = 0.287 acres (approx).

1 square mile = 640 acres 510 acres = (510 / 640) = 0.797 square mile (rounded) If the 510 acres of land are in a square plot, the plot would be 0.893 miles, or about 4,713 ft on a side.
