First. You have to look at what kind of proportionality it is.It is an Inverse Proportion.so you see the rate of change is 2.3
X can always be used a 1 .
1. 3 foot
2. 4 yard
3. 1 yard
4. 4 foot
5. 6 foot
6. 108 inch
7. 7.5 foot
8. 66 inch
9. 216 inch
10. 36 foot
11. 3.75 foot
12. 30 yard
The answer is 36in because that’s the pathagreom you need to use to find the answer
If 10 feet = 2.5 inches
then 1 feet = 2.5/10 = 0.25
therefore 12 feet = 3 inches
In short the answer is 3 inches on the blueprint
