the adjacent side of a parallelogram are in the ratio 3:7 and its perimeter is 100 cm . find the side of the parallogram .

Adjacent sides of parallelogram are in the ratio 3:7.

Perimeter = 100 cm

Perimeter of a parallelogram is 2(Length+Breadth) = 100
2(7x+3x) = 100
2(10x) = 100
x = 5

Thus, length = 7x = 7×5 = 35
breadth = 3x = 7×5 = 15

Hence, the answer.

  • -2
