    The perimeter of a parallelogram is 180 cm. One side exceeds another by 10 cm. The sides of the parallelogram are

    A) 40 cm, 50 cm         

    B) 45 cm each

    C) 50 cm each          

    D) cannot be determined

    Correct Answer: A

    Solution :

    Let one side be x cm. Then, adjacent side is \[(x+10)cm.\] \[\therefore \] \[{{90}^{o}}\] \[{{60}^{o}}\]or\[\therefore \] \[\frac{AB}{BC}=\frac{PQ}{QR}\]  \[\angle 4=\angle 2\]
