If it's 5$ for 10 feet, then you need to find the perimeter of the field and convert to feet. 100yds = 300ft, and 60yds = 180ft. the perimeter would be 300ft +300ft+180ft+180ft because you need all four sides. Now divide that by 10, because it's 5$ for every 10 feet, not every foot. When you divide, it would be 96$.
