Solve the problem.A school consists of five separate buildings, represented by the vertices in the graph below. There are paths between the buildings as shown. The graph also shows the length in tens of meters of each path. School administrators want to cover some of these paths with roofs so that students will be able to get from each of the buildings to every other building without getting wet when it rains. To minimize the cost, they must select paths to be covered in such a way that the total length to be covered is as small as possible. Use Kruskal's algorithm to determine which paths they should cover. Also, determine the total length of pathways which must be covered under your plan.
