Question

What are the dimensions of the product

Answer 1

The correct answer is B

Explanation:

2 x 2

Answer 2

2 X 2

Explanation:

We are given two matrices with different dimensions and are asked to determine the dimensions of the result.

Here we must know the rule to be applied to the product of the matrices.

Let us say that there are two matrices A and B whose dimensions are given as .

`A_(m * n)`

`B_(n * p)`

Where C is the product of A X B then the dimensions of C will be given as

`C_(m * p)`

Hence in our problem the dimensions of first matrix is 2 X 3 and that of second matrix is 3 X 2

Hence The dimensions of product of the Matrix will be

2 X 2

So the right answer is B)
