Hello!
To find the answer, you'll need to subtract 1.32 from 2.2. You can do this by using a calculator or by writing down on a piece of paper. First you'll need to add a zero to the end of 2.2 (2.20) since you are subtracting a 3 digit number from a 2 digit number. Once you've subtracted you should find how much the sapling grew in a year
The sapling grew 0.88 meters tall in the last year
I hope this helps!
