In the diagram,  triangle BDF and ACE  have the same area. If  DB = 2, BA = 4, and AE = 3, find the length of EC.

Except ACE is a straight line.  Typo?

In the diagram, triangles BDF and FCE  have the same area. If  DB = 2, BA = 4, and AE = 3, find the length of EC.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If [BDF] = [FCE] then [ABC] = [ADE]

 

[ADE] = 1/2(6 * 3) = 9

 

1/2[4 * (3 + EC)] = 9

 

EC = 1.5
