Find the perimeter of the triangle below. Round your solution to 2 decimal points. A (-3, 6) B (3, 2) C (3, 2) If a graph is needed let me know. Thank you.
must be a typo because two of the points are the same
If one point is described two times then these three points can't form a Triangle, therefore perimeter will be 0.

Yes. The diagram is wrong. B is (-3,2)
find the distance between AB BC and CA using distance formula and just sum it up u'll be getting the perimeter
^^^ Distance between two points =
Because your image is screwed up, here's your figures: AB = A(y) - B(y) = (6) - (2) = 4 BC = C(x) - B(x) = (3) - (-3) = 6 AC = sqrt(4^2+6^2) = sqrt(16+36) = 7.2 Perimeter = AB + BC + AC = 4 + 6 + 7.2
Sorry...2 decimal places makes it 7.21, not 7.2 So the perimeter is 4+6+7.21
