If A is a 3×2 matrix and B is a 2×4 matrix, the order of the product AB is:
- A. 3×4
- B. 2×2
- C. 4×3
- D. Product not defined
Answer: A) 3×4
Explanation: For matrix multiplication, if A is m×n and B is n×p, then AB is m×p. Here m=3, n=2, p=4, so AB has order 3×4. The product is defined because columns of A equal rows of B.
