The first thing we must do for this case is to find the perimeter of the figure. We have then that the perimeter is: P = ((35) * (280/180) * pi) + 45 P = 216.04 yards. Then, As David runs the field three times then: d = 3 * P d = 3 * 216.04 d = 648.12 yards. Answer: he covers a distance of 648.12 yards
