He will only take 3 rest periods, each of which last 30 minutes so he rests for 1 hour 30 minutes. Because the route takes 9 hours without rests, the duration with rests is 1 hour 30 minutes + 9 hours = 10 hours 30 minutes. 18:30 - 10:30 = 8:00.
888×333= 295704 which is your length and the next step is to multiply your length times your width which would be 295704×333=262585152. So your FINAL ANSWER IS 262585152 METERS SQUARED
