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.
