The answer is 17cm by 20cm.
The original area is 460cm (20x23), minus 120cm gives a new area of 340cm.
20cm-3cm=17cm and 23cm-3cm=20cm
17cmx20cm = 340cm

It is between 3.1 and 3.17 or 3.2 if you want it by hundredths.

This is because 3.16 is 3.1600000 and many more zeros but 3.16227766 is slightly over that so it would be between 3.1 and 3.17.
