Answer:

Area of ABFE  : Area of EFCD ::  (3a + b) :  (a + 3b)

Step-by-step explanation:

AB =  a cm

CD = b cm

E & F mid point

=> EF ║ AB ║ DC

& EF = (AB + DC)/2 = (a + b)/2

Area of ABFE = (1/2) ( a  + (a +b/2)) =  (1/4) (3a + b)

Area of EFCD = (1/2) ( (a +b/2) + b) =  (1/4) (a + 3b)

=> Area of ABFE  : Area of EFCD ::  (1/4) (3a + b) : (1/4) (a + 3b)

=> Area of ABFE  : Area of EFCD ::  (3a + b) :  (a + 3b)

option B is correct
