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?
