Question

If matrix $A$ is a square matrix, then the possible number of elements in $A$ is

• A. $8$
• B. $16$
• C. $24$
• D. $36$

Answer 1

Answer: (B), (D)

$36$

We know, for a matrix of order $m\times n$ to be a square matrix, $m=n$
So, total number of elements $=mn=m^2$ or $n^2$ (a perfect square)
