E is the midpoint of AB. AD:DC = 2:1. Area of BEC: Area of CDE : area of AED = ?

@perl
@jim_thompson5910
I'm not even sure of what they're asking exactly.
do they want the area of AED or do they want the ratio of the areas (if so, which areas?)
find the ratio of the areas stated in the question
@jim_thompson5910 CEA and ADE 90 degrees correct?
I don't think there is enough info to say yes or no
maybe you can upload a picture or diagram
ive given all the provided info including a diagram
there was not a diagram provided, sometimes its easier if we see the original
I cant upload the original, what ive drawn is the given diagram
thanks :)
If triciaal's assumption is correct, and we can say CEA and ADE 90 degrees, then the book authors would have put in these square angle markers |dw:1419814038490:dw| IF that assumption is true, then there is a way to connect the areas to form ratios. However, that info isn't given so I don't think it's safe to assume that.

there is no assumption, e is the midpoint and that's it
I think since BE = AE then EC is the perpendicular bisector so that would make it 90 degrees
it isn't given
triciaal, you can have a bisector that isn't perpendicular
CBE = CAE this has to do with similar figures but need to match the correct sides for the ratio. given the proportion 2:1
just draw altitudes. area or BEC = area of BEA (the two triangles share a common altitude)
|dw:1419814777437:dw|
|dw:1419814942411:dw| base of BEC is BE, height is XC, base of AEC is AE, height is XC. equal bases, equal heights.
