The location of four buildings on a coordinate grid are as follows: Building 1 is at (−5, −3) . Building 2 is at (−5, 5) . Building 3 is at (4, 5) . Building 4 is at (4, −3) . A bike courier begins at building 1 and then delivers packages to building 2 and then building 3, and then building 4. Then she bikes back to building 1. The path between each building is a straight line. One unit on the coordinate grid equals 100 feet. What is the total distance the courier biked? Enter your answer in the box.
