Question

The two sides of parallelogram are in the ratio of 3:4.The length of the parallelogram is 4.2cm.Find its perimeter.​

Answer 1

Answer:

19.6 cm

Step-by-step explanation:

Hey mate!! Here is your answer-

Let the sides be= 3x:4x

Now= l=3x=4.2 cm

x=4.2/3

x=1.4 cm

So 4x= 1.4 X 4

B=5.6 cm

Now perimeter of parallelogram= 2(l+b)

=2(4.2+5.6)

=2(9.8)

=19.6 cm

Hope this helps you.
