Expert Answer:
Since A is of order m by n and AB is defined,
the number of rows in B is equal to the number of columns in A. so the number of rows in B is n.
Again A is of order m by n and BA is defined,
the number of columns in B is equal to the number of rows in A. so the number of columns in B is m.
Hence, tthe order of the matrix B is n by m.
