To identify the dimensions of a matrix first count the number of rows, then the number of columns.
For example, for the above matrix you count the number of rows (they go horizontally from left to right), and there are 3. Then you count the number of columns (they go vertically from left to right) and there are also 3. Therefore you have a 3 by 3 matrix! Any matrix with the same number of rows as columns is a perfect square matrix.
This matrix would be a 4 by 3 matrix!
