What are the dimensions of the product?

1 x 2
2 x 2
3 x 2
3 x 3

Answer 1

2 x 2

Explanation:

Given the dimensions of the first matrix are 2x3 and the dimensions of the second matrix are 3x2, then the dimensions of the product will be 2x2.

Remember that the dimensions of a matrix are read by rows*columns.

The product of an m×n matrix and an n×k matrix is an m×k matrix
