Given :-
The perimeter of a parallelogram is 180cm. One of its sides is greater than the other by 30cm.
To Find :-
Length of sides
Solution :-
Let the smaller side be x
Greater side = x + 30
Perimeter = 2(l + b)
180 = 2(x + 30 + x)
180/2 = x + 30 + x
90 = 2x + 30
90 - 30 = 2x
60 = 2x
60/2 = x
30 = x
Therefore
Breadth = 30 cm
Length = 30 + 30 = 60 cm
