Answer 1

this is your answer this will help you

Answer 2

SOLUTION

GIVEN

The order of matrix A is 4 × 2 and the order of matrix B is 2 × 4

TO DETERMINE

The order of matrix A × B

CONCEPT TO BE IMPLEMENTED

Two matrices A and B can be multiplied if

Number of columns of A = Number of rows of B

EVALUATION

Here it is given that the order of matrix A is 4 × 2 and the order of matrix B is 2 × 4

Since Number of columns of A = Number of rows of B = 2

So the matrices A and B can be multiplied

Hence the order of A × B is 4 × 4
