Question

Can someone explain how to solve this

Answer 1

1 : 33.75

Explanation:

6.4 inches ⇒ 18 feet

6.4 inches ⇒ 18 x 12 = 216 inches

scale used

= 6.4 : 216

= 1 : 216 ÷ 6.4

= 1 : 33.75

Answer 2

The scale is simply the ratio between the distances in the plan and the actual distances. So, first of all, let's convert all lengths to the same unit measure:

`18\text{ ft} = 216\text{ in}`

So, the scale is

`(216)/(6.4) = 33.75`

which means that one inch in the plan is the same as 33.75 inches in the real world.
