Explanation:
If one price is 2 times the other one, that means it's equal to 2 of those parts. Let's decide our total wire by three to account for the larger part.
Now we know the shorter piece is 30 cm. To find the longer piece, multiply the shorter piece by 2.
Recap:
Shorter Piece: 30 cm
Longer Piece: 60 cm
That's all there is to it! hope this helps.
