Order of the Matrix is given by #(2, 3)#

Matrices are defined as a rectangular arrangement of numbers.

Since it is rectangular group(also known as an array), we can say that it is 2-dimensional.

The two dimensions here are the number of rows (m) and the number of columns (n) respectively.

Order of a Matrix tells us how many rows and columns are there in our Matrix.

If we call our Matrix #A,# and we have #color(red)m# rows and #color(red)n# columns then we can write our matrix #color(red)A# as

#color(blue)(A_(m xx n))#

In this case, Order of the Matrix is #color(blue)((m xx n))#

The given Matrix has ..

Rows = #2#

Columns = #3#

Hence,

Order of our Matrix is given by #(2, 3)#
