2. "I have grown 10 cm from last year." - This sentence uses the present perfect tense, indicating an action that started in the past and continues up to the present. It suggests that the growth has been ongoing since last year.
3. "I grew by 10 cm from last year." - This sentence uses the past tense and includes the preposition "by," which indicates the amount of growth. It indicates a specific amount of growth that occurred in the past.
