Age is a number plus 岁 (suì): 我二十五岁 means "I am twenty-five". The verb 是 is usually left out.
Grammar rule: Age with 岁

How you ask depends on who you ask. 几 expects a small number, so 你几岁? to an adult sounds like a question for a child.
nǐ jǐ suì?
How old are you? (to a child)
nǐ duō dà?
How old are you? (to a peer)
nín duō dà niánjì?
How old are you? (to an older person)
我二十岁 (wǒ èrshí suì). The verb 是 is usually left out.
A peer: 你多大? (nǐ duō dà?). A child: 你几岁? (nǐ jǐ suì?). An older person: 您多大年纪? (nín duō dà niánjì?).
Before measure words two becomes 两, and 岁 behaves like one: 两岁, 两个月, 两本书.
