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

Perimeter = 100 cm

Perimeter of a parallelogram is 2(Length+Breadth) = 100

$\Rightarrow $2(7

*x*+3

*x*) = 100

$\Rightarrow $2(10

*x*) = 100

$\Rightarrow $

*x*= 5

Thus, length = 7

*x*= 7$\times $5 = 35

breadth = 3

*x*= 7$\times $5 = 15

Hence, the answer.
