To solve the equation \( w^2 = 118 \), we first need to find two perfect squares: one that is less than 118 and one that is greater than 118.

1. **Identify perfect squares**:
- The perfect square less than 118 is \( 100 \) (since \( 10^2 = 100 \)).
- The perfect square greater than 118 is \( 121 \) (since \( 11^2 = 121 \)).

2. **Calculate the square roots**:
- The square root of \( 100 \) is \( 10 \) (i.e., \( \sqrt{100} = 10 \)).
- The square root of \( 121 \) is \( 11 \) (i.e., \( \sqrt{121} = 11 \)).

3. **Write down the range**:
- Since \( 10^2 < 118 < 11^2 \), we can conclude that \( w \) must be between \( 10 \) and \( 11 \).

Now, we can calculate the square root of \( 118 \) to find \( w \):

\[
w = \sqrt{118} \approx 10.863
\]

4. **Round to the nearest tenth**:
- Rounding \( 10.863 \) to the nearest tenth gives \( 10.9 \).

Thus, the final answer is:

\[
w \approx 10.9
\]

So, \( w \) is between \( 10 \) and \( 11 \), with the rounded result being \( 10.9 \).
