please post the OA - esp when you are posting some question as a doubt.

The answer is most likely to be option 4 - if this is the correct answer- I shall post the solution.

REFER to the figure - I assumed AB =12 AND AD = 1/2 AB = 6
Area of HGF =1/2 * 3 * 6 = 9
AREA OF Triangle GJK = 1/3 * 9= 3

And the area of the rectangle = 6 * 12 = 72

tHUS the ratio required = 3 :72 or 1 :24
