Question

to attention sides of a parallelogram are in the ratio 2 is to 3 that perimeter of the parallelogram is 72 find the length of the each of its sides​

Answer 1

Answer:

21.6 cm , 14.4 cm , 21.6 cm , 14 .4 cm

Step-by-step explanation:

GIVEN THAT,

Two adjacent side of a parallelogram are in the ratio 3:2

Let the common multiple be x

Then Adjacent sides are 3x and 2x

We know that,

Opposite angles of parallelogram are equal

Therefore,

Other two sides are 3x and 2x

Now,

Also given that

Perimeter = 72 cm

Sum of all sides = 72 cm

3x + 2x + 3x + 2x = 72

10x = 72

x = 72/10

x = 7.2 cm

=> 3x = 3×7.2 = 21.6 cm

=> 2x = 2×7.2 = 14.4 cm

HENCE,

Length of sides of given parallelogram are

21.6 cm , 14.4 cm , 21.6 cm , 14 .4 cm

Answer 2

Answer:

Step-by-step explanation:

Two adjecent sides of a parallelogram are in the ratio 2 : 3

Let length of one side=2x

Length of another =3x

Perimeter of the parallelogram=72

2(2x+3x)=72

10x=72

X=7.2

So sides of the parallelogram are 14.4 & 21.6
