Question

The scale of a map is 1:40 000. find the actual area in km2 (km squared) for this area on the map.
15cm2

Answer 1

Step-by-step explanation:

1cm on a map represents 4000000

5cm on a map represents =5×4000000=20,000,000‬cm

1km=1000m

1m=100cm

∴1km=1000×100=100000cm

∴100000cm=1km

∴20,000,000‬cm=

100000

20,000,000‬

km=200km

Thus, the actual distance between two towns is 200km

Answer 2

Answer:

1cm on a map represents 4000000

5cm on a map represents =5×4000000=20,000,000‬cm

1km=1000m

1m=100cm

∴1km=1000×100=100000cm

∴100000cm=1km

∴20,000,000‬cm=

100000

20,000,000‬

km=200km

Thus, the actual distance between two towns is 200km.
