Question

Two sides of a parallelogram are in the ratio 3:7 and the perimeter of the parallelogram is 200cm . Find the length of the adjacent sides of the parallelogram​

Answer 1

Answer:

1st side=30cm,2nd side=70cm

Explanation:

Let the two sides be 3x and 7x.

Perimeter=200cm. (Given)

Now, parameter of a parallelogram =2(a+b)

Perimeter = 2(a+b)

200cm. = 2(3x+7x)

200cm =2(10x)

200/2 =10x

100. =10x

100/10. = x

Therefore, x=10cm

Now, 1st side =3x (put value of x =10)

=3X10=30cm

2nd side = 7x

=7X10=70cm
