Rows are always horizontal, and columns are vertical. It's easier to remember when you think of rows of seats (like in a sports stadium) which are horizontal, and buildings have tall columns, which are vertical.
The first matrix has 3 rows and 2 columns, the second matrix has 2 rows and 3 columns. Two matrices can only be multiplied together if the number of columns in the first matrix is equal to the number of rows in the second matrix. In the example shown there are 3 rows in the first matrix and 3 columns in the second matrix. And also 2 columns in the first and 2 rows in the second. Multiplication of the two matrices is therefore possible.
