Solution

Let us draw the diagram from the given information.

As we are given that distance between their feet is 12 m
.

Now we get a right angled triangle DCE.

Let us applying the Pythagoras theorem we get,

Substituting the values we get,

Let us take the square root we get,

Therefore, distance between their top is .
