The location of four buildings on a coordinate grid are as follows: building 1 is at (−5, −3)(−5, −3) . building 2 is at (−5, 5)(−5, 5) . building 3 is at (4, 5)(4, 5) . building 4 is at (4, −3)(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?
