Information about the area is not enough to determine the perimeter.
640 acres is 1 sq mile. The smallest perimeter possible is if the area is in the shape of a circle and in that case the perimeter would be 3.54 miles = 18717 feet. If the area is a square the perimeter would be 4 miles = 21120 feet. If it is a rectangle, then any value greater than 4 miles.
640 acres = 27,878,400 square feet.
the answer is clearly 86557485 mega tons
