8. The following figures GUNS and RUNS are parallelograms. Find and
. (Lengths are in cm)
Diagonals of a parallelogram bisect each other, therefore,
OR = ON i.e. 16 = x + y ….(1)
and OU = OS i.e. y + 7 = 20 ….(2)
From (2), y = 20 – 7 = 13 cm
putting y = 13 in (1),
we get 16 = x + 13 or x = 16 – 13 = 3 cm
Hence x = 3 cm and y = 13 cm
