Question

# A matrix A = (aij) m x n is said to be a square matrix if-

- m = n
- m n
- m n
- m < n

## The correct answer is: m = n

### To find a condition for square matrix.

For a square matrix, number of rows is equal to number of columns of a matrix.

m=n

Therefore, for the given matrix to be square matrix, m = n.
