To solve the problem, we will use the fact that the two shapes are similar. In similar shapes, corresponding sides are proportional.

The corresponding sides are:
- 18 m corresponds to 22 m
- 81 m corresponds to \(x\) m (the missing length).

We can set up a proportion to find \(x\):

\[
\frac{81}{x} = \frac{18}{22}
\]

Now, solve for \(x\) by cross-multiplying and simplifying:

\[
81 \times 22 = 18 \times x
\]

\[
1782 = 18x
\]

\[
x = \frac{1782}{18} = 99 \, \text{m}
\]

Thus, the missing length \(x = 99\) meters. However, this answer doesn't match any of the provided options, suggesting a possible error or issue with scaling in the diagram.
