E and F are points of intersection of the side DC =3X and AB =Y, what is the ratio of the area of the triangle BEF to the area of the rectangle ABCD
(a) 2:3
(b) 1:6
(c) 1:4
(d) 2:1

• If ABCD is a rectangle,shouldnt AB be equal to CD?

• ans:1:4
  GIVEN THAT AB=Y SO FB=Y/2,
  AREA OF TRIANGLE=AREA OF RECTANGLE
  1/2*l*b=l*b(since both lengths are same)
  1/2*b=b
  1/2*y/2=y
  1:4

• 1:6
  Area of triangle BEF= 6 times Area of Rectangle ABCD

• please explain which points are e and f

• since it is given here that abcd is arectange then how can lines ab and cd insect with each othr as they are parralle line ????

• here AB and DC are two opposite sides of rectangle.so Y=3x
  so area of triangle=1/2*y/2*y/2=y^2/8
  area of rectangle =y*y/2=y^2/2
  so ratio=(Y^8/2)/(Y^2)/2=1:4..we can do it in reverse way means in form 0f 3x also..result will be same.
