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. 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?
