A carnival ride consists of four circular cars- A, B, C, and D- each of which spins about a point at its center. The center points of cars A and B are attached by a straight beam, as are the center points of cars C and D. The two beams are attached at their midpoints by a rotating arm. The figure shows how the beams and arm can rotate. 



A plan for the ride uses a coordinate plane in which each unit represent on meter. In the plan, the center of car A is (-6, -1), the center of car B is (-2, -3), the center of car C is (3, 4), and the center of car D is (5,0). Each car has a diameter of 3 meters. 



1. What is the maximum length of the ride? 



2. Describe the shape and dimensions of a fence that will be appropriate to enclose the ride. Justify your answer. 



Please explain :/
