Solution

The correct option is A True
In (ΔPOS) and (ΔSOR)
PO=OR (diagonal bisects eachother)
POS=SOR (900)
OS=OS (common side)
POS(ΔSOR) (SAS congrience)
Area of POS = Area SOR
In (ΔQOR) and (ΔPOQ)
OP=OR (diagonal bisects eachother)
POQ=QOR (900)
OQ=OQ (common side)
QOS(ΔQOR) (SAS congrience)
Area of QOS = Area QOR
Area of parallelogram PQRS=Area of POS+Area of POQ+Area of QOR+Area of SOR
=Area of SOR+Area of SOR+Area of POQ+Area of POQ
=2SOR+2AreaofPOQ
2POS+2QOR=2SOR+2POQ
Area(POS)+Area(QOR)=Area(POQ)+Area(SOR)
