PQRS is a parallelogram. Find x and y. Given length in cm.

 Q.1. PQRS is a parallelogram. Find x and y. Given length in cm.

Ans.:

We known that the diagonals of a parallelogram bisect each other.

Therefore, we can write ,

x+7=20   .........(i)  and  x+y=16 ........(ii)

x+7=20

or, x=20-7

or, x=13

Putting the value of x=13 on equation (ii) we get, 

13+y=16

or, y=16-13

or. y=3

Therefore, x=13 cm and y=3 cm
