Hello,

I have three points in 3-dimensional space (and cartesian x,y,z coordinates). Can somebody please tell me the formula for finding out the AREA of the triangle formed by them?

Thanks a lot in advance.

Use Heron's Formula (http://www.mathopenref.com/heronsformula.html). You only need the three side lengths, and those are easy.
