Apark 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) . 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? enter your answer in the box.
