Margarete leaves her home to run several errands. Her house, the supermarket, the municipal building, and the post office are represented on a coordinate grid with the following locations: Margarete's house is at (−5, 3) . The supermarket is at (2, 3) . The municipal building is at (2,−2) . The post office is at (−5,−2) . Margarete drives from her home to the supermarket, then to the municipal building, then to the post office, and then back home. The paths from one location to another are straight lines. Each unit on the coordinate grid represents 1 mile. What is the total distance Margarete has traveled?
