`A ,\ B ,\ C ,\ D` are mid-points of sides of a parallelogram `P Q R Sdot` If `a r\ (P Q R S)=36 cm^2,` then `a r(A B C D)=` `24\ c m^2` (b) `18\ c m^2` (c) `30\ c m^2` (d) `36\ c m^2`

Text Solution

Verified by Experts

A, B, C and D are the midpoints of sides of a `|\|`gm PQRS.
area(`trianglePQRS`)=`36cm^2`
The area of ||gm formed by joining AB, BC, CD and DA =`1/2ar(|\|`gm PQRS)
=`1/2xx36`
=`18cm^2`
Hence, option (b) is correct.
