Two sides of a parallelogram are in the ratio 5 : 3. If its perimeter is 64 cm, find the lengths of its sides.

Let x be the common multiple.


According to question, sides will be 5x and 3x.


Perimeter =


64 = 2 (5x + 3x)


64 = 16x


x = 4


5x = 20 cm


3x = 12 cm


So, sides will be 20 cm and 12 cm.
