Question

The matrix \( A = [a_{ij}] \) of size \( m \times n \) is a square matrix if:

• A. \( m = n \)
• B. \( m<n \)
• C. \( m>n \)
• D. None of these

Hint:

A matrix is square if the number of rows is equal to the number of columns. Always check if \( m = n \) for a matrix to be square.

Answer 1

The Correct Option is A

A matrix \( A \) is called a square matrix if the number of rows is equal to the number of columns, i.e., the size of the matrix is \( m \times n \), where \( m = n \). Thus, the matrix will be a square matrix when \( m = n \).
