Product Of Two Vectors

Area of parallelogram having adjacent sides and = 20 s units

Now, area of parallelogram



s units

The scalar triple product is given by the determinant of a matrix whose rows (or columns) are the components of vectors . That is, Step 1: Expand the determinant
Use the first row to expand the determinant:
Step 2: Evaluate each minor
Step 3: Add the results

The magnitude of the cross product is given by: Substitute the given values: Thus, . Thus, the correct answer is .
