EBA is 0.25 ABCD and ABC is 0.5 ABCD does that help?

To use reply #2, you must know that triangles are similar.

So the area of is one-forth the area of - September 3rd 2011, 04:08 PMkingmanre: Find the Area of a Portion of a Square
I am aware that fact and also ABC is 0.5 of ABCD but got stuck from here on.

Yes I know it can be done using Similar Traingles facts but I wonder how it can be done by a simpler approach. This is what required in this question for students who have not studied similar triangles.

Hi kingman,

Draw a line fromE parallel to AB meeting AC @ G. The area you seek consists of one squareand 1/2 square side lengths a/2 plus triangle EFG where a is length of large square side.Your problem is then to find the altitude of EFG
