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 $3 \times 2$ and order of matrix $B$ is $2 \times 4$.
So, the order of $A B$ will be the "number of rows of $A \times$ number of columns of $B^{\prime \prime}=3 \times 4$
