Answer:
Correct option is B)
A,B,C,D are point of sides of parallelogram PQRS area (PQRS)=36 cm2ar(ABCD)=?
AP=21SP, BP=1QR
PS=QR,21PS=21QR
area (△ABC)=21(△PQCQ)
area (△ADC)=21ar(ACRS)
area △ABC+area(△ADC)=21area(APCQ)=21area(ACRS)
area(ADCD)=21area(APCQ)+(ACRS)area
area(ABCD)=21area(PQRS)
area(ABCD)=21(36)
=18 cm2
