Area of the parallelogram in which the two adjacent sides are A and B is given by
Correct answer: A. AB sin θ
- A. AB sin θ
- B. Ab
- C. AB cos θ
- D. Zero
Explanation
If area of parallelogram formed by two vectors A and B is given by the magnitude of their cross product: Area of parallelogram = |A x B| So, the area of the parallelogram formed by two adjacent sides A and B is the magnitude of the cross product of these vectors.

About Vectors and Equilibrium
Vectors have magnitude and direction, unlike scalars, and are combined by head-to-tail or parallelogram methods. Work covers rectangular components, equilibrium when the resultant force is zero, the scalar product for work and projections, and the vector product for torque and cross-product direction using the right-hand rule.
