How much should a 15 year old girl who is 5 feet tall and does fencing 5 days a week weight?

I am 15 years old and my height is 5 feet. I am an athletic person so I have an athletic body. I practice fencing 5 days a week for 3 hours daily. I would like to know what my ideal weight should be. Thanks|||you should weigh between 110-120.
