Step-by-step explanation:

$\huge\blue{Answer}$

The ratio of the two sides

The ratio of the two sides = 3:5

let's suppose that one side of the parallelogram be 3x and another one be 5x

Now as we know that in parallelogram opposite side are same therefore

Sum of all sides = Perimeter of parallelogram

3x + 5x + 3x + 5x = 168 cm

10x + 6x = 168 cm

16x = 168 cm

$x \: = \frac{168}{16} \\ x = 10.5 \: cm$

Now putting the value of X in the given ratio

$3x \: = 3 \times 10.5 = 31.5 \\ 5x \: = 5 \times 10.5 = 52.5 \\ 3x \: = 10.5 \times 3 = 31.5 \\ 5x = \: 10.5 \times 5 = 52.5 \\ \\ \\ so \: the \: sides \: of \: parallelogram \: will \: be \: =$

31.5 , 52.5 , 31.5 and 52.5
