Question

If a matrix has 6 elements, the number of possible orders it can have are

• A. 3
• B. 4
• C. 6
• D. 2

Answer 1

The correct option is B

4

If a matrix is of order m × n, it has mn elements. Thus, to find

all possible orders of a matrix with 6 elements, first find all ordered pairs of natural

numbers, whose product is 6.

Thus, all possible ordered pairs are (1, 6), (6, 1), (3, 2), (2, 3)

Hence, the number of possible orders are 4.
