Review your length formula. Find the lengths of the sides, and add them up. I'll give you one side, you do the other two.
AB = √((5-(-2))^2+(-3-2)^2) = √(7^2+5^2) = √74
The coordinates of the vertices of ABC are A(-2,2) B (5, -3) and C (-4,-1) Identify the perimeter of ABC. Round each length to the nearest tenth before adding.
I am totally lost!
