Answer:

\huge\boxed{25.2\  m}

Step-by-step explanation:

In order to find the length of the missing side here, we must note that these triangles are similar.

Therefore their lengths are proportionate to each other.

So,

\frac{27.6}{11.5} = \frac{x}{10.5}

We can solve for x by cross multiplying.

10.5\cdot 27.6 = 289.8\\\\289.8 \div 11.5 = 25.2

Hope this helped!
