Question

the length of one side of a parallelogram is 2/3 times the length of its adjacent sides.if the perimeter of a the parallelgram is 20cm find the sides of parallelogram ​

Answer 1

Answer:

Sides of parallelogram are 8,12,8,12

Step-by-step explanation:

Let a and b be the adjacent sides of a parallelogram.

Given,  b=2/3*a

Perimeter =2(a+b)=20

2(a+  2/3*a)=20

a+  2/3*a=10

5/3*a=20

a=20*3/5

⇒a=12

b=2/3*a

b=2/3*12

⇒b=8

Sides of parallelogram are 8,12,8,12
