Question:
$A=\left[a_{i j}\right]_{m \times n}$ is a square matrix, if
(A) $m (B) $m>n$ (C) $m=n$ (D) None of these
Solution:
The correct answer is C.
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, $A=\left[a_{i j}\right]_{m \times n}$ is a square matrix, if $m=n$.
