For educational websites, you can explain the problem like this:

This problem involves using proportions to find the height of the child. Given that the water tower's height and shadow length are known, you can set up a proportion:

\[
\frac{\text{Height of water tower}}{\text{Shadow of water tower}} = \frac{\text{Height of child}}{\text{Shadow of child}}
\]

Plugging in the known values, you get:

\[
\frac{60}{90} = \frac{\text{Height of child}}{6}
\]

Solving this proportion will give you the height of the child.
