The matrix product is .
Multiplication of two matrices possible if the number of columns in the first matrix equals the number of rows in the second matrix.
\The dimensions of the matrix are
and the number of columns in the matrix are
.
The dimensions of the matrix are
and the number of the rows in the matrix is
.
The number of columns in the matrix equals the number of rows in the matrix
.
Thus, matrix product is possible.
Its dimensions are .
.
