How much should a 5.1 11 year old girl weight?

I'm 11, about to turn twelve next month. Anyway i am really athletic but u cant tell from looking at me. I'm sort of chubby but when i show people my skill they see me and treat me as a different person. I'm about 5.1 - 5.2 and i weigh 127. I'm proud of myself and you should to. lots of people worry about how much they weigh but the way i see it you only have one shot at life so don't waste it by complaining. i hope this helped. bye.
