MCQ
If the matrices has 13 elements , then the possible dimension (order) it can have are:
  • ✓
    1 × 13 or 13 × 1
  • B
    1 × 26 or 26 × 1
  • C
    2 × 13 or 13 × 2
  • D
    None of these
✓

Answer

Correct option: A.
1 × 13 or 13 × 1
As we know the number of elements in a matrix = (no.of rows) × No.of columns.

Therefore for 13 elements the rows and columns could only be (13 × 1) or (1 × 13)
