Question

construct a parellogram PQRS with PQ=6cm,QR=4cm,QS=7cm​

Answer 1

Answer:

If PQ=6cm, QR=4cm, then how can be QS=7cm.

Draw the figure in your copy and mark the figure PQRS and then understand it properly that QS can't be one line.

Wrong question.

Answer 2

Step-by-step explanation:

ANSWER

⇒ We know that opposite sides and angle of parallelogram are equal.

⇒ And adjacent angles of parallelogram are supplementary. By using these properties we are going to construct a parallelogram.

⇒ Draw a line segment PQ=5cm

⇒ Construct an angle of 70

∘

at point Q.

⇒ Cut off QR=4cm

⇒ Construct an angle of 110

∘

at point P.

⇒ Cut off PS=4cm

⇒ Join RS

⇒ Thus PQRS is a required parallelogram

⇒ Let a=5cm and b=4cm

⇒ Perimeter of parallelogram PQRS=2(a+b) =2(5+4)=18

⇒ The perimeter of parallelogram PQRS=18cm
