Question:

Let $A$ and $B$ be matrices of orders $3 \times 2$ and $2 \times 4$ respectively. Write the order of matrix $A B$.

Solution:

Since, the order of matrix A is 3×">××2 and order of matrix B is 2×">××4.

So, the order of AB will be the "number of rows of A ×">×× number of columns of B" = 3 ×">×× 4
