Question

4. The length of a skyscraper on a map is 7 mm. The scale used in the map is 1mm = 1/56km. Calculate the actual length of the building in metres.

Answer 1

Step-by-step explanation:

Length of the skyscraper on the map = 7millimetres

Scale of the map = 1mm =1/56km

Actually length of the skyscraper = 7 x 1/56

7 and 56 cancel, making 7 as 1 and 56 as 8

so the length of the skyscraper is 1/8km.

1/8 km is 125 m.
