I figure she is around 14-16 years old. But like the first टिप्पणी दे कहा it officially states she is 16 years old at the bottom of the 4th page in the वीरांगना, अमेज़न preview.
I tried to figure that out after seeing the movie, and decided that she was probably anywhere from 16 to like, 21 या 22. दिया that 16 seems a लोकप्रिय age for डिज़्नी princesses as well as for marrying girls off way back in the day, I kind of settled on that. Like Ariel, she can pass for a 16-year-old. And then I flipped through the junior novelization at Barnes & Noble and discovered that I was right. ^^
