Solution
The correct option is B 1 : 2
If a triangle and a parallelogram are on the same base and between the same parallels, then the area of the triangle is equal to half the area of the parallelogram.
△FAR and parallelogram CART are on the same base AR and between the same parallels AR and CT. ∴12(ar△FAR)=ar(CART) ⇒ar(△FAR)=2×ar(CART) ∴ar(△FAR)ar(CART)=12 =1:2
