Answer» Solution : Given: $AD : DB = 2 : 3$ and Area of $ABC = 100$ sq.cm. From the given information, we can easily find out that triangle ADE and triangle ABC are similar. So, by EQUATING we get Area of ADE / Area of ABC $= AD^2 / AB^2$ Area of ADE / Area of ABC $= AD^2 / AB ^2$ Area of ADE / 100( given) $= 4/ 25$( given) Area of ADE $= (4×100)/25$ Area of ADE $= 400/25 =16 $sq.cm. Now, Area of QUADRILATERAL BDEC = Area of triangle ABC - Area of triangle ADE $= 100 - 16$ $= 84$ sq.cm. The correct OPTION is 1). 84
