Question
$A = [a_{ij}]_{ m \times n}$ is a square matrix, if
✓
Answer
We know that if a given matrix is said to be a square matrix if the number of rows is equal to the number of columns.
Therefore, $A = [a_{ij}]_{ m \times n}$ is a square matrix if $m = n.$
Therefore, $A = [a_{ij}]_{ m \times n}$ is a square matrix if $m = n.$
