Answer:
The answer is 44.
Explanation:
2 sides are going to be 12 meters long unless said otherwise, so you would add up 12 + 12 = 24.
Now, you would write 10 meters wide for 2 sides which would give you 20, because 10 + 10 = 20, a well known fact; I'm sure.
When you are done with these steps, you add 20 + 24 to get the answer 44.
