In the diagram, triangle BDF and triangle ECF have the same area.. If DB = 2, BA = 3, and AE = 5, find the length of line EC. Diagram is below.

Area of   ADE =  1/2 5 x 5 = 25/2

 

 

area of  ABC = 1/2  3 * AC  = 25/2

                             AC = 25/3

 

    AC - AE = EC = 25/3 - 5 = 10/3
