Answer:
B
Step-by-step explanation:
To find the constant of proportionality between y and x, divide 
for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.
Using the method above, you should get:
Chart A = 2/5
Chart B = 1/5 (Correct Answer!)
Chart C = N/A

The width in inches would be 12, because of the formula:
length x width = perimeter
so you would do it reverse!
perimeter/length = width
so, 144/12 = 12
<u><em>16.1 is the final answer. </em></u>
<em>Product- it's going to be multiply by the numbers only.</em>
<em>You can also round up to the nearest tenths is 16.0</em>
