How do I find the area of a parallelogram with the given vertices K (1, 3, 2) L (1, 4, 4) M (4, 9, 4) N (4, 8, 2) I have to use the cross product, but I'm pretty lost. Please help!

Please help! For any , equals the area of the parallelogram defined by the points . Thanks to the above, the area of is : compute the vectors, the cross-product, and then the norm.
what do i do after i find the cross product of KL and KM ??
