Enter your answers in the boxes.
The matrix is a × matrix.

Answer 1

Answer:

• The dimensions of a matrix are the number of rows × the number of columns of the matrix.

• For the example below, the the matrix is 3 × 4.

Explanation:

The dimensions of a matrix is the number of rows × the number of columns of the matrix.

Your matrix is garbled. Thus, to help you I will work with an hypothetical matrix.

Assume the matrix:

        $\left[\begin{array}{cccc}1&0&0&0\\2&4&0&3\\0&0&0&9\end{array}\right]$

That matrix has four colums and 3 rows.

For instance, the first colum is:

            $\left[\begin{array}{c}1\\2\\0\end{array}\right]$        Thus, it has 4 columns.

And the second row is:

          $\left[\begin{array}{cccc}2&4&0&3\end{array}\right]$         Thus, it has 3 rows.

Hence,  the matrix is 3 × 4.

The first number is the number of rows and the second number is the number of columnns.

Answer 2

The dimension of matrix is $3*4$

Dimension of matrix :

The dimensions of a matrix are the multiplication of number of rows and the number of columns of the matrix.

Given matrix are,

                           $A=\left[\begin{array}{cccc}1&0&0&0\\2&4&0&3\\0&0&0&9\end{array}\right]$

Since, the above matrix has  3 rows and 4 column.

Thus, the dimension of matrix is $3*4$
