The perimeter of a parallelogram is 150 cm. One of its sides is greater than the other by 25 cm. Find the length of the sides of the parallelogram.
Perimeter of the parallelogram = 150 cm
Let one of the sides = x cm
Other side = (x + 25) cm
We know that opposite sides of a parallelogram are equal and parallel.
Perimeter = Sum of all sides
x + x + 25 + x + x + 25 = 150
4x + 50 = 150
4x = 150 – 50
x = 
Therefore sides of the parallelogram are 25 cm and 50 cm.
