Hi...☺

Here is your answer...✌

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
