Hi,

I found this question and I could do with some help regarding the answer. It is:

Nine lines are drawn parallel to the base of a triangle to divide each of the other sides into 10 equal segments. If the area of the largest region is 38, find the area of the original triangle.

I believe that it must be ratios and something like:

(Sorry bad drawing!)

Ratio of sides =

Therefore, ratio of areas =

Therefore area =

Am I right? I feel that this is rather inadequate and too simple.

Thanks very much for any help!
