Adding the right and left fences, the total perimeter of the field would approximately be 628.32 feet + 325 feet + 325 feet = 1278.32 feet. 5280 feet make a mile. So one would have to cover 5280/1278.32 = 4.13 perimeters or laps of a baseball field to cover a mile. That's how we reached the answer 4 laps!
