To determine

To find: The area of the parallelogram with one corner at ${\text{p}}_1$ and adjacent sides → ${\text{p}}_1{\text{p}}_2$ and ${\text{p}}_1{\text{p}}_3$

For, ${\text{p}}_1 = \left(1,2, - 1\right),{\text{p}}_2 = \left(4,2, - 3\right),{\text{p}}_3 = \left(6, - 5,2\right),{\text{p}}_4 = \left(9, - 5,0\right)$
