Plot tyhe points, and use the distance formula to find the sides.
For example, if the points are ABC, then
AB = √((-3+9)^2 + (-6+3)^2) = √(36+9) = √45
find the other two sides and add them up.
Or if, as I suspect C = (-9,-4), then you have a right triangle, and the legs are easy to find the lengths. Then just find the hypotenuse and add 'em up.
