Step-by-step explanation:
perimeter of parallelogram = 2(l + b) = 30
l and b are the adjacent sides of parallelogram
one side is 5 more than the smaller side
l = b + 5
2(l + b) = 30
l + b = 30/2
l + b = 15
substitute l = b + 5 in above equation
b + 5 + b = 15
2b + 5 = 15
2b = 15 - 5
2b = 10
b = 10/2
b = 5
l = b + 5
l = 5 + 5
l = 10
therefore the sides of parallelogram are 10cm and 5 cm
Hope you get your answer
