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
