на 11 см.

Пошаговое объяснение:

на скільки я зрозумів 2дм. - це 2 дитциметри. Якщо це так то 2 дм. = 20 см. , а 20 см. більше 9 см. НА 11 СМ.

20-9=11 см. (або так)

1: I'm really interested in cars, so this was an amazing day for me. I still can't believe that my first driving experience was in a Lamborghini and an Aston Martin! I've got a video of the whole thing. I'm glad about that, because on the day there's no time to look at the cars properly. As soon as you finish, the next driver gets in. I was a bit
upset about that. Liam
