Question

24. One side of a parallelogram is 5 times its adjacent sides. If the perimeter of the parallelogram is 80cm. Find the sides of the parallelogram.
​

Answer 1

Answer:

x = 20/3 cm (6.666666 cm)

and 5x = 20/3*5

            = 100/3 cm (33.3333 cm)

Step-by-step explanation:

Let one side be x

Therefore, the adjacent side = 5x

Perimeter = sum of all sides

80 = x + 5x + x + 5x (since opposite sides are equal in a paralleogram)

80 = 12x

80/12 = x

x = 20/3 cm (6.666666 cm)

and 5x = 20/3*5

            = 100/3 cm (33.3333 cm)
