Location 2 is at (−4, 4) . Location 3 is at (3, 4) . Location 4 is at (3, −1) . The paths from one location to another are straight lines. One unit on the coordinate grid equals 10 yd. Betsy starts at location 1 and goes to location 2, then location 3, and then location 4, and then returns back to location 1. What is the total distance Betsy has traveled?
