Please help, will be greatful :)

what level is this question?

2.3cm

Step-by-step explanation:

We can see that it's a right triangle, similar to the one on the bottom left. Because the long side is 4 times longer, the short side is 4 times longer as well. So it's around

0.57cm*4= 2.28cm

Rounding to the 1st decimal place 2.3cm.

Please note, that rounding to 2 decimal places the answer 2.28cm could be inaccurate, e.g. if the real length would have been close to 0.574(9) or 0.565, but all of those options still round to 2.3cm.
