Let the adjacent sides of the parallelogram are 7x and 3x.
Hence, the other two adjacent sides are also 7x and 3x.
 perimeter = 100 cm
⇒ 3x + 7x + 3x + 7x = 100 cm
⇒ x = 5
so required sides are sides are 35 cm, 15 cm, 35 cm and 15 cm.

sweety u are superb
hahaha not as much as u Mr.Intelligent :P
yeah I know , but you are better than in other fields .. so overall superb and mind Blowing :p
The adjacent sides of the parallelogram are 7x and 3x.
other are also the same.
your p. = 100 cm
then u apply the linear equations method.
3x*2+ 7x*2=100
standard form = 3x+7x+3x+7x=100
20x =100
so the sides are 15cm,35cm, 15cm,35cm.
hope this helps u !!!!!!!!!!!!!!
