⇒Given :- PQRS is a parallelogram where ST=8cm,PQ=4cm, and RQ=6cm.......
⇒To find:- Find QU...........?.....
⇒Sol:- PQRS is a parallelogram. So its opp. Sides will also be equal and parralel [PQ = SR and PS =QR]....
⇒area of parallelogram = Base × height.
..so ar.of PQRS = PQ × ST = 8 ×4 =32 cm² ..
⇒ We can also say that - THE BASE AND ALTITUDE OF PARALLELOGRAM PQRS iS ALSO RQ AND QU..
⇒so substitute the numbers..... ⇒AR .OF PQRS = RQ ×QU = 32 cm²=6×QU....= QU = 32/6 = 5.33 or 5.3 cm.....
There fore the ans is 5.3 cm.
