Question

Dimension of a Matrix State the dimension of the matrix.

$\left[\begin{array}{ll}1& 0\\ 0& 1\end{array}\right]$.

Short answer

The dimension of matrix is 2 x2.

Step-by-step solution

Step 1.Given information.

The given matrix $\left[\begin{array}{ll}1& 0\\ 0& 1\end{array}\right]$

Step 2. Write the dimension for the given matrix.

So, we know that the matrix $\left[\begin{array}{ll}1& 0\\ 0& 1\end{array}\right]$ has 2 rows and 2 columns.

Therefore, we say that matrix has dimension 2 x2,2 rows by 2 columns.
