$A=left[a_{i j} ight]_{m imes n}$ is a square matrix, if

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 $m=n$.
