A city planner designs a park that is a quadrilateral with vertices at J(-1,1), K(1,3), L(5,-1), and M(-1,-3). There is an entrance to the park at the midpoint of each side of the park. A straight path connects each
entrance to the entrance on the opposite side. Assuming each unit of the coordinate plane represents 10
meters, what is the total length of the paths to the nearest meter? Round your answer to the nearest
whole number.
The total length of the paths is approximately
meters.

For each proportion find the unknown number x 1/5/8=×/15
