I believe that when you calculate a triangles length that you must add all the sides together to get the perimeter.

Let's say that 3m is side A and 18m (that's what 4 times 3 is) is side B.

Therefore, A + B + C = 27m

The C would be the third side, which seems to be what you're looking for.

So, 3m + 18m = 21m

27m - 21m = 6m
