Area of a triangle formed by vectors

  1. May 27, 2007 #1
    1. The problem statement, all variables and given/known data

    What is the area of a triangle formed by the vectors 2i-j+3k and i+2j+2k.

    3. The attempt at a solution

    I didn't know it was possible to find the area with only 2 vectors!:confused:
    Can somebody please show me how?

    I imagine the third side of said triangle is the length between both of the vectors.

    That said, this seems to be a tricky problem because of the three dimensions involved, I'm thinking about it now.

    Did you check your text book in linear algebra? This is standard problems.
