Find the area of the parallelogram with vertices:

P(0,0,0), Q(-3,0,-1), R(-3,1,0), S(-6,1,-1)

2. Relevant equations

A=BH

3. The attempt at a solution

I think I know why this is incorrect, but i dont know what else to try.

I found vector PQ and called it a, vector PR called it b, vector PS called it c.

Then did a dot (b cross c)=3 but thats incorrect.

I basically found the volume, but idk how to find the area.

Any suggestions I should try?
