Chapter 16.1, Problem 10WE

To determine

To write: the dimensions of given matrix.

Answer to Problem 10WE

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

Explanation of Solution

Given information:

Given matrix,

  $\left[\begin{array}{cc}a& b\\ c& d\end{array}\right]$

Calculation:

Consider the given matrix.

  $\left[\begin{array}{cc}a& b\\ c& d\end{array}\right]$

Dimension of a matrix with m rows and n columns can be written as

  $m\times n$

Here, in the matrix the number of rows is 2 and number of column is 2.

So, the dimension of the matrix is $2\times 2$ .
