anonymous · Answer

diagonal lengths are 14 and 16, not side lengths

OHHHH... so that's why I was having so much trouble. Thank you! *doh*

it looks kind of like a law of cosine problem
then a projected height problem

then area of rectangle
i might be wrong though cause im not really thinking much

anonymous · Answer

Yeah it is :) thanks
