Answer 1

We have the next matrix

$\begin{bmatrix}{-1} & {9} & {8} \\ {3} & {3} & {8} \\ {} & {} & {}\end{bmatrix}$

And we must find its size.

The size of a matrix is the number of rows by the number of columns.

In this case, we have 2 rows and 3 columns

So, the size of the matrix is

$2\times3$

ANSWER:

$2\times3$
