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 =2△SOR+2Areaof△POQ ∴2△POS+2△QOR=2△SOR+2△POQ Area(POS)+Area(QOR)=Area(POQ)+Area(SOR)
