A matrix with order m×n has:
- m = number of rows
- n = number of columns
Total elements in a matrix = m×n
The matrix has 8 elements.
Checking which orders give exactly 8 elements:
(A) 8×1
Rows × Columns =8×1
=8 elements
This is a possible order.
(B) 5×3
Rows × Columns =5×3
=15 elements
This is not a possible order.
(C) 6×2
Rows × Columns =6×2
=12 elements
This is not a possible order.
(D) 2×4
Rows × Columns =2×4
=8 elements
This is a possible order.
Only options (A) and (D) give exactly 8 elements.
The possible orders are 8×1 and 2×4.
