The plan width is
in.

Answer 1

4.5 inches

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

`(4)/(plan\,\,width)=(192)/(216)\\ plan\,\,width=(216)/(192)(4)=4.5\,\,inches`
