let width =x
length = 5x-3
..
Perimeter = 2(x+5x-3)
Perimeter = 2(6x-3)
=12x-6
...
new rectangle
width = 3x
length = 2(5x-3)
perimeter = 2(3x+2(5x-3))
perimeter = 2(3x+10x-6)
perimeter = 6x+20x-12
...
6x+20x-12=12x-6+92
6x+20x-12x=-6+92+12
14x=98
/14
x=98/14
x=7 cm. the width of original rectangle
length = 5x-3 = 5*7-3 = 32cm
