It is hard to tell the age of a turtle because there are so many factors that can determine their size. A turtle fed every day that is kept outside will grow faster than a turtle fed let's say every other day and kept indoors. Whether a turtle is allowed to hibernate or not also affects their size. If I were to guess its age, I would say maybe two or three years old.
Hope this helps, Steve
