What are the dimensions of the matrix?. i need help pls​

Answer 1

5 X 5

Explanation:

The dimensions of a matrix
`$ \implies` number of rows and columns of that matrix. If it is as an
`$ m * n $` (read as
`$m$` by
`$n$` it means that it has
`$m$` number of rows and
`$n$` number of columns.

In the given problem, the rows and columns are 5. So, we write it is a
`$ 5 * 5 $` matrix. We call it a Square matrix, since the number of rows equals the number of columns.
