A quarter mile is, by definition, a fourth of a mile. It is 1,320 feet or 402.3 meters. On a standard-sized Olympic track, it is a little more than a single lap.
Each acre is 43,560 square f â¦ eet   Therefore, one quarter of a section is 640/4 x 43,560 = 6,969,600 square feet.   Alternatively, you can see that a square mile cut into quarters would be 4 half-mile by half-mile squares. A mile is 5,280 feet, so each square would be (1/2 x 5,280)2 = 6,969,600 square feet.
