Can someone me, i'm lowkey struggling.

Yea of course at the top it says that you have to find length which it isn't very hard to do what you gotta do is since it's 49(2) (that's suppose to be you know small and at the content of the nine) you have to simplify it which is 2,401 and the perimeter around the square are four sides so you multiply 2,401 and 4 which is 9,604

The answer is c. 7 (i think) i’m almost sure though
