Gigi's home is located on the grid with the points (-6, 2), (-1, 2), (-7, 4) and (0, 4). She is planning to paint the entire roof of her home. Each unit on the coordinate grid represents 5 feet. Each can of paint can paint up to 45 feet of open space. How many cans of paint must Gigi purchase to paint the entire roof of her room? Pls show work and explain!
Brainliest to the first person who gets the question right and explains it!
