To have a different rectangle with the same perimeter you just have different measurements. If you need an example let me know!
1 5/10 meters is equivalent
Y= 3x - 10
<span>3x + 2y = 16
3x+2(3x-10)=16
3x+6x-20=16
9x-20=16
9x=36
x=4
y=3x-10
y=3(4)-10
y=12-10
y=2</span>
Depends are you finding x or other variables
