1.	ABCD is a trapezium in which AB \|\| CD, AB = 16 cm and DC = 24 cm. If E and F are respectively the midpoints of AD and BC, prove that ar(ABFE) = 911 ar(EFCD).
Answer» ABCD is a trapezium in which AB \|\| CD, AB = 16 cm and DC = 24 cm. If E and F are respectively the midpoints of AD and BC, prove that ar(ABFE) = $\frac{9}{11}$ ar(EFCD).
