Mass Build Well Livin' Life: Is the carpet area misleading?

Mass Build Well Livin' Life — I'm seriously fed up with the carpet area issue. Builder ne brochure mein jo dikhaya, possession ke time actual usable space kaafi kam nikla. My current 2BHK in Indirapuram feels bigger, honestly. It's like they shortchanged on usable area. Is the price jump worth it for a 3BHK when carpet area itna kam hai? Plus, maintenance charges kya high hain yahan? Anyone else faced this carpet area discrepancy or hidden costs after moving in? Kya kiya aapne?
