If a matrix A is of order 3 × 2 and matrix B is of order 2 × 3, then the order of matrix AB is :

1. 3 × 2

2. 3 × 3

3. 2 × 3

4. 2 × 2

Let C be the resultant matrix.

We know that,

The resultant matrix is equal to the number of rows of the first matrix and the number of columns of the second matrix.

A_{3 × 2} × B_{2 × 3} = C_{3 × 3}.

Hence, Option 2 is the correct option.
