IN PARALLELOGRAM OPPOSITE SIDES ARE EQUAL .
PERIMETER=48 CM
RATIO OF ADJACENT SIDES ARE=3:5=3X:5X
SUM OF 2 TIMES OF ADJACENT SIDES EQUAL TO PERIMETER.
THE PERIMETER= 6X+10X=48
                             16X=48
                                 X=3
THEREFORE, THE SIDES ARE  9CM , 15CM , 9CM , 15CM

So we know parallelogram has equal sides so let the sides be 

3x and 5x 

so perimeter = 48
⇒2(3x + 5x)= 48
⇒8x = 24
⇒x = 3

so the sides are 9 cm,15 cm,9 cm,15 cm
