The adjacent sides of a parallelogram are represented by co-initial vectors

2\hat i + 3\hat j\,and\,\hat i + 4\hat j

. The area of the parallelogram is

View answer and explanation

Correct option: A

5 units along z- axis

Option A (5 units along z- axis) is correct because the area of the parallelogram is the magnitude of the cross product of the vectors, which results in a vector along the z-axis.
