    Q1. When calculating the area of a parallelogram using vector products, how does reversing the order of vectors affect the result?

    • A) A x B = B x A
    • B) A x B = -(B x A)
    • C) A x B = 0
    • D) A x B = 1

    Answer: A x B = -(B x A)

    Explanation: A x B = -(B x A), meaning it is anti-commutative. Option A is wrong because the magnitudes are equal but directions opposite.
