A new patio is in the shape of a square. On a scale drawing, the vertices of the patio's coordinates are: (6,1.5), (6,-5.5), (-1,-5.5 )- , (-1,1.5 ). How long is each side of the patio?
Seven units long. The distance between 2 sides, in this example is 6, and -1. The distance between 6 and -1 is 7, so when you add units, you get 7 units.
