To multiply B and A, the number of columns of B must matc the number of rows of A.

When we can multiply two matrices?

When we multiply two matrices, A and B, we multiply the rows of matrix A by the columns of matrix B.

Now, the number of elements in a row of a matrix, is equal to the number of columns (and the number of elements in a column is equal to the number of rows).
