It should be 12×18. 1:3 means you take where it's at, at 1 and multiply it's size by 3.
7.6=w/12
w=7.6(12)
w=91.2
x/2=20
x=20(2)
x=40
8.3x=41
x=41(8.3)
x=340.3
54=r/3
r=54(3)
r=162
Its linear , if side is x then perimeter is 4x
I hope this helps, if you have any further questions don't hesitate to ask
The lowest common denominator for 8 and 12 is 24. So you would need 3 packages of hotdogs and 2 packages of buns.
