See one possible response
Sam is thirty. The table is two metres long.
You need a few clear facts about people, furniture and a nearby route. All measurements in this lesson are invented practice details.
What you will practise
- Ask and answer about age and height.
- Ask and answer about an object’s length.
- Ask for a distance and distinguish it from age or length.
Say your answer. Then check the model. Your answer can be different if it fits the task.
Ask about age and height
Use How old is …? for age and How tall is …? for height. Put is or are before the person or thing. In answers, a number and a useful unit give clear information.
How old is your cousin? She’s twenty-eight.
How tall is the tree? It’s six metres tall.

Ask about length
How long is …? can ask for the length of an object. The named object makes the meaning clear. Answer with a length, not a clock time. Use is with one object and are with more than one.
How long is the table? It’s two metres long.
How long are the shelves? They’re one metre long.
Match is or are to the object
It’s two metres long.
They’re one metre long.
Ask about distance
Use How far is …? to ask about distance. You can add from here to show the starting point. A reply such as It’s three kilometres away gives the distance clearly.
How far is the shop from here?
It’s about two kilometres away.
