Question

If the order of matrix A is 2 x 3. And the order of B is 3 x 4, then the order of matrix AB is ?

Answer 1

Answer:

2×4

Step-by-step explanation:

solution:

a is 2×3

b is 3×4

AB=2×4

Answer 2

Answer:

AB is of the order 2 x 4.

Step-by-step explanation:

Given that the order of matrix A = 2 x 3

and the order of matrix B = 3 x 4

We know that multiplication of matrices is only possible when the number of columns of first matrix = number of rows of the second matrix

and the resultant matrix will be of the order (n x m)

where n is the no. of rows of first matrix

and m is the no. of columns of second matrix.

Here, no. of columns of A = 3

and no. of rows of B = 3

Therefore, matrix AB can be formed and it will have the order 2 x 4
