A park is represented on a map with the following vertices coordinates:


Vertex 1 is at (−4, −1)(−4, −1) .


Vertex 2 is at ​ (−4, 5)(−4, 5) ​.


Vertex 3 is at (2, 5)(2, 5) .


Vertex 4 is at (2, −1)(2, −1) .


Linsey jogs along the the edge of the park in order from vertex 1 to vertex 2 to vertex 3 to vertex 4 and then back to vertex 1. One unit on the coordinate grid equals 20 yd.


What is the total distance Lindsey jogged?
