$A=\left[\begin{array}{l}a_{i j}\end{array}\right]_{m\times n}$ is a square matrix, if

A

$m < n$

B

$m > n$

C

$m=n$

D

None of these

Solution

It is known that a given matrix is said to be a square matrix if the number of rows is equal to the number of columns.

Therefore, $A = {\left[ {{a_{ij}}} \right]_{m\, \times n}}$ is a square matrix, if $\mathrm{m}=\mathrm{n}$
