Question

ABCD is a trapezium in which AB II DC such that AB= a cm and DC= b cm . If E and F are the midpoint of AD and BC respectively. Then ar( ANEF) : ar(EFCD)= ?

Answer 1

e and f are mod points of ad and bc respectively hence EF||AB (mid point theorem )
similarly EF||DC
therefore EF||Ab ||DC
and also EF=Ab=DC=area of trapezium
hence there areas will also be equal
