Answer: 576 inches or 48 feet
Step-by-step explanation:
set up a proportion where 
so you get drawingAB = 24 in
actualAB = 18 feet = 18 * 12 in = 216 in
drawing perimeter = 64 in
so plug these in to get
rearrange to get 
and solve to get 576 inches or 576/12 = 48 feet
When the second number is divided by the first, the result is ...
First table
9/3 = 3
12/4 = 3
20/5 = 4 . . . . result is not consistent. NOT a proportional relationship
Second table
25/20 = 1.25
30/24 = 1.25
40/32 = 1.25 . . . . result is consistent. A PROPORTIONAL RELATIONSHIP
Third table
12/4 = 3
15/5 = 3
24/6 = 4 . . . . result is not consistent. NOT a proportional relationship
Fourth table
4/3 ≈ 1.33
9/6 = 1.5
16/12 ≈ 1.33 . . . . result is not consistent. NOT a proportional relationship
If you mean by a(t)=2t+9 is the acceleration function then we integrate...
v(t)=2t^2/2+9t+c where c is vo and we are told that that is -7 so
v(t)=t^2+9t-7 integrating again we get:
s(t)=t^3/3+9t^2/2-7t+c where c is the initial position which is 8 so
s(t)=t^3/3+9t^2/2-7t+8 which neatened up as
s(t)=(2t^3+27t^2-42t+48)/6
we want area =circumference*something
dividing our first equation by 2*pi
substituting in the second equation
simplifying
