The overall is the sum of the orders of each component.



still don't get it but guessing A

What is there to get? I think your problem may be that you don't know how to read the rate law equation. The equation is 1st order with respect to A (I know that because the exponent of A in the rate law equation is 1) and it is 2nd order with respect to B (similarly, the exponent is 2). Then 1 + 2 = 3. So 3rd order over all.
