Well it looks like you have enough information there to come up with a function that represents the area of that polygon. After that see where that function has a maximum. That is take its derivative and find critical points, and plug them into your original function, and see what values you get.

You need to show some work of yours, if you want to get more help!

Cheers!

… a bit at a time ! …

Hi mercedesbenz! :smile:

This is one of those problems that is a bit complicated to do all in one go.

So simplify it … do a bit at a time!

Hint: fix A B and D, and just find the best place for C.

Solve that, and the rest of the problem becomes obvious. :smile:
