The figure shows an aerial view of a playground. If David runs around the field three times, he covers a distance of yards.

There isn't much we can do about this problem judging by the lack of information but we can have a general way of answering this problem. If we are given a polygon, or shapes with sides, we add up all the sides to get the perimeter. If it's a circle, get the circumference. Then with the perimeter we multiply this with 3. That is how we answer the problem.
