Water the Yard!

Use the file above to design a sprinkler system for the backyard in the photo. Try your best to cover all of the grass and minimize the water that goes into a neighbors' yards or the driveway. Also make sure that the garages are not getting hit by the sprinklers. Your goal is to cover at least 75% of the grass with your six sprinklers. You will need to calculate the area of grass that needs to be covered and the area that your sprinkler system reaches.
