Chapter 10.3, Problem 10E

To determine

To calculate: Dimension of the matrix.

Answer to Problem 10E

The dimension of the given matrix is $2\times 2$ .

Explanation of Solution

Given information:

Matrix:

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

Calculation:

The given matrix is:

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

This matrix has $2$ rows and $2$ columns so it is $2\times 2$ matrix.

  $2\times 2$ Indicates the matrix consist of $2$ rows and $2$ columns.

Thus the dimension of the given matrix is $2\times 2$ .
