For matrix
Number of elements = 2 × 2 = 4
We can calculate number of elements by counting,
or from order of matrix
Number of elements = Number of Rows × Number of columns
Similarly, for matrices
Number of elements = 3 × 2
= 6
For
Number of elements = 3 × 3 = 9
Number of elements = 1 × 6 = 6
Number of elements = 5 × 1 = 5
Number of elements = 3 × 4 = 12
If a matrix has 12 elements, what are the possible order it can have?
Since matrix has 12 elements
Hence, possible order are
1 × 12, 2 × 6, 3 × 4, 4 × 3, 6 × 2, 12 × 1
