Apark 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?
