Question

in a parallelogram ABCD,adjacent sides are in the ratio of 2:5 and its perimeter id 56cm .find the leangt of the side of parallelogram ABCD.​

Answer 1

Answer:

Length=8cm

Breadth=20cm

Step-by-step explanation:

Let we take length=2x

                  breadth=5x

Perimeter=56cm

Acc to question;

2(2x+5x)=56cm

2(7x)=56cm

14x=56cm

x=56/14

x=4cm

Therefore,

Length=2(4cm)

           =8cm

Breadth=5(4cm)

            =20cm

Answer 2

Answer :

2x + 5x + 2x + 5x = 56

14x =56

x=56/14 = 28/7

4

2 *4 = 8cm

5*4 = 20cm
