1. And the answer is 14.14 m, which is the same as 10 m * √2.
2. And you see, we know that the old variance would be a 100 m², the µ thinks
3. therefore, it's 200 m² because I told you that just add up.
4. If we go to the standard deviation, we take the square root of this.
5. This factors into 2*100 m², so we take the square root of this,
6. we get back the 10 m on the right side and you get the √2 on the left side,
7. which gives me the 14.14 m for the standard deviation.
