11. Calculate the area of the parallelogram having the vertices(adsbygoogle = window.adsbygoogle || []).push({});

(1,2,3),(4,-2,1),(-3,1,0), and (0,-3,-2).

To solve this problem I need to find two vectors that share a common point? Then I can take the magnitude of the cross product of those two vectors to find the area of the parallelogram...no problem.

The problem is how do I know what two vectors will have a common point? Am I just suppose to think in 3d and see it?
