Answer:
i got 36:8, 54:12, and 72:16
Step-by-step explanation:
the one with 3/10 left has more
because 1/5 is equal to 2/10 and 3/10>2/10
They are both right becuase if you just take away 1 from 20 and 10 you get 2 and 1. For the 4:2 one take away 1 and mutiply by 2 equalling 4:2 but they are still the same thing.
Perimeter:
18+4x+12+5x

Part B:
