$3$ by $3$ or $3xx3$ matrix

A matrix dimension is based on the number of rows by the number of columns.

If a matrix has $m$ rows and $n$ columns, it is known as a $mxxn$ matrix.

In the given example, as both rows and columns are three, it is a $3xx3$ matrix

What is the dimension of the matrix [(-3,17,-22),(9,31,16), (20,-15,4)][(-3,17,-22),(9,31,16), (20,-15,4)]?
