Toolbox:
• The number of elements in an m x n matrix will be equal to mn
Number of elements in a matrix=product of rows & column.
$\qquad\qquad\qquad\qquad\qquad\quad=m\times n$
In the above matrix we have 3 rows and 3 columns.
Hence no of elements=$m\times n$
$\qquad\qquad\qquad\quad=3\times 3$
$\qquad\qquad\qquad\quad=9$
