$r = [\begin{array}{c} m + 1 & t \\ n - 2 & y \\ 3 - p & q \end{array}]$

خطوة 1

A matrix is a rectangular arrangement or array of elements. The dimensions of a matrix, $m \times n$ , identify how many rows and columns a matrix has. $m$ represents the number of rows and $n$ represents the number of columns. Assuming that the matrix name is $r$ , the matrix dimensions are written as $r_{m \times n}$ .

خطوة 2

The number of rows is $3$ .

$m = 3$

خطوة 3

The number of columns is $2$ .

$n = 2$

خطوة 4

The given matrix has dimensions $m \times n = 3 \times 2$ .

$r_{m \times n} = r_{3 \times 2}$
