The perimeter of a parallelogram is 102 cm. If one side is greater than the other by 9 cm, find the lengths of all sides of the parallelogram.

Dear Student, 

let length=l and breadth=bGiven , l=9+b2l+b=102........inow putting value of l in equation i29+b+b=1029+2b=512b=51-92b=42b=21 cm l=b+9=21+9=30 cm  hence in parallelogram opposite sides are equal  hence  length of two sides=30 cm breadth of two sides =21 cm 

Regards
