The area of a square is 121 sq feet. What is the length of its sides? Would I find this by dividing 121 by 4?

No. the area of a square is s^2, where s is a side length
s^2=121
take the square root of each side
s=11ft 
the side times the side = 121
Something times itself is 121
It is not 9 because 9*9 = 81
It is not 10 because 10*10 = 100
Is it 11?
What is 11 times 11? 
No.
The area of a square is the side squared.
Take the square root of 121 to find the length of a side. 
The answer is 11.
