Minimum stilt car parking size of apartment as per RERA or Greater Noida Authority?

I live in Greater Noida West of Uttar Pradesh. Please help my builder just now allotted 2 parking in 14ft (w) X 15 ft (L). I asked to management about this they said it is approved by greater Noida authority and as per the approved map of building. My question is can authority approve builder 2 stilt parking spaces in 14ft (w) X 15 ft (L)?. Earlier there was only 1 stilt parking marked. Now I see a partition. I talked to AOA of society but they are saying you can change the parking and go to basement. But i don't want to change the parking as this suits my need. Also there are 6 inches pipes in one side of wall. I searched online about the regulations passed by G N authority and found this https://www.greaternoidaauthority.in/files/attachments/blawsengpart4.pdf In this if you go to Table 5 (page 4) you can see 1 ECS = 13.75 Sq mtrs for group society but mine is 9.75 Sq Mtrs I also found this link about RERA https://www.moneycontrol.com/news/business/real-estate/parking-woes-this-is-how-rera-distinguishes-parking-space-and-garage-2289589.html
