Answer:

7.17 cm

Step-by-step explanation:

If the width is x, the length is twice this = 2x

And

Perimeter = 2 (W + L)

Perimeter = 2 ( x + 2x)

Perimeter = 2 (3x)

Perimeter = 6x

43 = 2 ( x + 2x )

43= 2 ( 3x)

43 = 6x

= 7.17 cm

Hope this helps i'm pretty sure this is how you do it :-)

The 2 equations are
18.20x+19.50y=230.10
and
x+y=12
where x is the months of original cost and y is months for new cost. Since you know that you paid for one year (12 months) you can make the second equation. Then you want to substitute the first equations x by making the second equation
x=(12-y)
18.20(12-y)+19.50y=230.10
218.40-18.20y+19.50y=230.10
1.30y=11.70
y=9
so that means you had the original rate for 3 months and the new one for 9 months
