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

Vertex 1 is at (−4, −1) .

Vertex 2 is at (−4, 5) .

Vertex 3 is at (2, 5) .

Vertex 4 is at (2, −1) .

Lindsey 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?
