Answer 2

Given :-

Two sides of parallelogram are in the 3:7 and its perimeter is 200 cm.

To find :-

The length of adjacent sides of parallelogram .

Solution :-

→The perimeter of a parallelogram is 2(l=b).

→ The opposite sides are equal in length.

so,  

⇒ 2(7x+3x)=200

⇒14x+6x=200

⇒20x=200

⇒x=200/20

⇒ x=10

→The sides will be  7x and 3x .

⇒ 7×10 and 3×10

⇒ 30and 70.

Hence required ans is  30cm and 70cm.
