Find the area of the parallelogram with the vertices A(3; 2), B(5; 4), C(4; 1). (Advice: Consider two vectors: both starting from the point A and ondir and C roc tivoy)

use vectors

If a = (2, -1, 2) and b = (3, 2, 1), answer the following. Vectors can be entered using either or the i, j, k from the Vectors %3D menu. (а) а х b 3 (b) The exact area of the parallelogram formed by a and b is (c) Sketch the vectors a, b, and a x b, along with the parallelogram formed by the vectors a and b. Submit with your handwritten work.

I really badly need the answer to this question.
