The area of a square is:
\(A = s^2\)
Where 's' is the side.
So plug in 49:
\(49 = s^2\)
Now we find the square root of both sides:
\(s = \sqrt{49}\)

So what's the square root of 49?

I don't understand :(

\(\sqrt{49}\)

7

Yes, that's correcct.
OpenStudy (anonymous):
Yes, 7 is your answer.

This is the formula for the Area of a circle:
\(A = s^2\)
To find the side length, we plug in the Area and solve for 's':
\(49 = s^2\)
Now we have to get rid of the exponent of 2, and to do that we find the square root of both sides, giving us:
\(s = \sqrt{49}\)
