John was visiting three cities that lie on a coordinate grid at (-4, 5), (4, 5), and (-3, -4). If he visited all the cities and ended up where he started, what is the distance he traveled? Round your answer to the nearest tenth. (like 3.2 or 5.7)

Answer 1

Clearly, the first two points lie in a horizontal line, so the distance between them is 8
Review how to find the distance between two points given the coordinates, then find the remaining two distances.
Add up the 3 sides.
Show your work so I can check it.
