Question

A square with side length
\[s\] has an area of
\[225\] square centimeters. The following equation shows the area of the square.
\[s^2 = 225\]
What is the side length of the square in centimeters?

Answer 1

To find the side length \( s \) of the square, we start with the equation given by the area of the square:

\[
s^2 = 225
\]

To solve for \( s \), we take the square root of both sides:

\[
s = \sqrt{225}
\]

Calculating the square root, we find:

\[
s = 15
\]

Thus, the side length of the square is

\[
\boxed{15} \text{ centimeters}.
\]
