let the x be puted on the ratio of the given side
3x, 5x
perimeter of parallelogram=sum of all sides
A/q
3x+5x=48
8x=48
x=48/8
x= 6
3x=3×6=18
5x=5×6=30
3x, 5x

One side 3x
and other side 5x
Perimeter=2(3x+5x)
2(3x+5x)=48
2×8x=48
16x=48
x=48/16
x=3
One side 3x=9
other side 5x=15
By cutting and adjoining the figure we get rectangle
Area of the rectangle =L×B
15×9=135
and other side 5x
Perimeter=2(3x+5x)
2(3x+5x)=48
2×8x=48
16x=48
