We know a parallelogram has equal opposite sides 

so let the longer side be l =9.5 cm
and the adjacent side be b

so we have perimeter = 2(l+b) = 30 ⇒ l+b = 15 ⇒ 9.5 + b = 15 ⇒ b = 5.5 cm

so the sides are 9.5 cm , 5.5 cm , 9.5 cm , 5.5 cm ANSWER

In parallelogram opposite sides are equals.So AB = DC = 9.5 cm.

Given perimeter of parallelogram = 30 cm
Let breadth be x

Perimeter of parallelogram = 2 ( Length + Breadth )
                                   30 = 2 ( 9.5 + x )
                                   15 = 9.5 + x 
                                   5.5 = x

Hence the each side of the parallelogram are 5.5 cm , 9.5 cm , 5.5 cm , 9.5 cm.
