A = [a_ ij ]_ m n is a square matrix, if: - Vidyadip

MCQ

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

A
$m < n$
B
$m > n$
✓
$m = n$
D
None of these.

✓

Answer

Correct option: C.

$m = n$

For $A = [a_{ij}]_{m \times n}$ to be square matrix.
number of row $s =$ number of columns
$\therefore m = n$
$\therefore (c)$ is correct.
