The graph shows the locations of Karen's, Amanda's, and Zaley's houses on a coordinate plane. Each unit on the graph represents 1 block.
A coordinate plane is shown. Amandas house is located at 1, negative 1, Karens house is located at 1, 5, and Zaleys house is located at 6, negative 1. Line segments connect the three points to form a right triangle.
Zaley is going to babysit for Amanda and Karen. How many total blocks will she travel if she goes to Amanda's house, then to Karen's, and finally back home? Round your answer to the nearest whole block.
