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!
