If a matrix has 5 elements, write all possible orders it can have.
Question:

If a matrix has 5 elements, write all possible orders it can have.

Solution:

We know that if a matrix is of order $m \times n$, then it has $m n$ elements.

If the matrix has 5 elements, then the number of elements will be $1 \times 5$ or $5 \times 1$, i.e. there will be 2 possible orders of the matrix.
