You could do it in your head.
EQUILATERAL!

12%262%2F9


You see?*



*Let me adjust what I said.
If you are in high school, you should be able to do this in your head. If in elementary school, maybe you are still dealing with Number Sense and common arithmetic, and seeing how to handle the 36 and the 2%2F3 requires skill that you have not had much experience with yet.

One will become accustomed to some products of 12 and see some simple computations to do on simple fractions, like cut %282%2F3%29 into three parts, or dividing it by 3...... %282%2F3%29%2A%281%2F3%29, easy enough to handle this in your head.
