Question

: Find the perimeter of a parallelogram if one of its sides is 3.2cm long and the adjacent Side is 3/2times of it ​

Answer 1

Answer:

16 cm

Step-by-step explanation:

side1=3.2

side2=3/2 of side1=3/2×3.2=4.8

Perimeter = 2*(side1+side2)

=2*(3.2+4.8)

=2*(8)

=16

Answer 2

Answer:

Your answer is 21.6 cm, 14.4 cm, 21.6 cm, 14.4 cm

Step-by-step explanation:

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
