Answer:
4.5 inches
Step-by-step explanation:
Given: plan length = 4 inches, actual width = 18 feet, actual length = 16 feet
To find: plan width
Solution:
1 feet = 12 inches
Plan length = 4 inches
Actual width = 18 feet= 18× 12 = 216 inches
Actual length = 16 feet = 16× 12 = 192 inches
Plan length/plan width = actual length/actual width
[tex]\frac{4}{plan\,\,width}=\frac{192}{216}\\ plan\,\,width=\frac{216}{192}(4)=4.5\,\,inches[/tex]
