The answer would be:
Korea: 6
Italy: 7
France: 8
6, 7, 8 are consecutive numbers because they go in the order that you would count from 1-x(an infinite number) with.
I hope this helped! If you have further questions don't be afraid to ask!

just need to multiply and axpand ?

The perimeter is 2(length) + 2(width), so 2(x+5) + 2(x+4) = 42 m. In solving for x, you find 6. Plug 6 back into your length and width where x originally was, and you find your length to be 11m, and your width to be 10m. Hope this helps!
