Can't decode Noida property prices, need help with areas and brokers

Honestly, I'm feeling completely overwhelmed trying to understand property pricing in Noida. Experion Developers ka Block A mein ek 2BHK dekh raha tha. Super area aur carpet area ka difference samajh nahi aa raha. Builders numbers inflate karte hain kya? For a ₹70-80L 2BHK, real carpet area kitna expect karna chahiye? Also, broker ke through jaana better hai ya direct builder se deal karein? Koi bolta hai broker better deal dilwata hai, koi kehta hai direct mein discounts milte hain. Kya experience raha hai aapka with hidden costs near possession?
