# Stretching Machine: Suppose you have a stretching machine which could stretch almost anything. For example, if you put a 5 metre stick into a (× 4) stretching machine (as shown below), you get a 20 metre stick.

Now if you put 10 cm carrot into a (× 4) machine, how long will it be when it comes out?

**Solution:**

Given, a stretching machine could stretch almost anything.

A 10 cm carrot is put into a (× 4) machine.

We have to find the length of the carrot when it comes out of the stretching machine.

Given, 5 cm stick put into the machine we get 20 metres stick.

Input = 5 cm

Output = 20 cm

So, 5 × 4 = 20 cm

Similarly, input = 10 cm

Output = 10 × 4

= 40 cm

Therefore, a 10 cm carrot comes out as 40 cm in length.
