Clearly, EF=AB+

DC

​  

=

a+b

​  

 

Area of Trapezium =

1

​  

(Sum of  parallel sides)×h

Let h be the height as shown in figure, then  

ar(Trap.ABFE):ar(Trap.EFCD)

⇒

​  

[a+

a+b

​  

]×h:

​  

[b+

a+b

​  

]×h

⇒

2a+a+b

​  

:  

2

2b+a+b

​  

 

⇒ 3a+b:a+3b  

Hence, this is the required ratio.
