Step 1- Determine the inner dimensions of both the matrices

The inner dimensions for both the provided matrices are represented by the number 3

02

– Determine whether the product is defined or not

As the inner dimensions of provided matrices are the same which means that the product for the provided matrices is defined.

03

Step 3- Write the dimensions that defines the product

As the numbers 4 and 2 represents the dimension that is outer so the multiplication between them represents the dimension related to product that is .4脳2
