1. The problem statement, all variables and given/known data 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?
