Question

If the area of quadrilateral ABED= 6/5, find the area of triangle DEC

BE=EF=FC

Answer 1

@oldrin.bataku

Answer 2

Well given that relation we see the height of our triangle is just \(2/3\) that of the side \(BG\). We know the area of our rectangle is given by \((DC)(BG)\) and we can infer the area of our triangle is just \(\frac12(DC)(2BG/3)=\frac13(DC)(BG)\) so \(1/3\) of the area of our rectangle.
