Detailed Solution

Given that, height of a building is 18 m and this building is represented by 18 cm on a map.
We know that scale is the ratio of the dimensions of the design or model to the actual dimensions i.e.,  Scale of map = Size Drawn Actual Size .
⇒  Scale of map =  18 cm 1800 cm ⇒  Scale of map =  1 100
