Is this a good workout plan?

So I just signed up for the gym, I stepped on the scale and I said enough is enough lol. So Monday's after work I'll do this little boot camp thing they have at the gym. This is for 45 min. Than maybe walk on the treadmill for 20. Wednesday I'll do Zumba for 45 min at the gym class than end my day with a 20 min treadmill walk. And lastly Friday I'll do another fitness class, the call it the "butt&gut" it's also for 45 min. Is that an effective workout plan? My goal is to lose 30 pounds by October. My trouble area is my stomach and back. I have a gut and back rolls.Not excessive but, not were I want to be. I know eating healthy is also part of this, but let's just talk about working out for now.
