Question

If matrix A has dimensions 2 x 5 and matrix B has dimensions 5 x 5, can matrix A and matrix B be multiplied?

yes

no

Answer 1

Yes they can be multiplied.


The main condition of matrix multiplication is that the number of columns of the 1st matrix must equal to the number of rows of the 2nd one.

If you multiply a matrix of 'n' x 'k' by 'k' x 'm' size you'll get a new one of 'n' x 'm' dimension.

here n = 2 and m = 5.

So , result will be matrix with dimensions 2 x 5.
