Is 55 kilos a good weight for a 11 year old girl who's 5.1 feet tall?

I'm 12 and I'm around 48 kilos to 50 kilos. Except I'm around 5'1? I don't think I'm average, but a bit above average. Am I? Thing is, I'm supposed to be answering this, yes, you're absolutely fine because you're tall, now if you were a 5'0-5'1 I think you'd need to watch what you eat...but you wouldn't be that obese or fat. Don't worry about your weight, you're 11. Just play around a lot and eat healthy at times, that's all. this persons write i am 11.....and im a little chubby i way about 114....and im 5'1. so ur like 118 and 5'4! isay ur pretty lean...cool 4 you:)
