Question

The scale of a map is 1: 10000000. on the map, the area of Slovakia is 4.9cm². Calculate the actual area of Slovakia and give your answer in km².​

Answer 1

Answer:

Representative Factor - 1:1000000

This means 1 cm on the map represents 1000000 cm on the actual ground

Area of forest on map =

4.6 \: {cm}^{2}4.6cm

2

1 \: {cm}^{2}1cm

2

on map represents

1000000 \times 1000000 \: {cm}^{2}1000000×1000000cm

2

on actual ground

Area of forest :

=1000000 \times 1000000 \times 4.6 \: {cm}^{2}1000000×1000000×4.6cm

2

(1 m = 100 cm)

=10000 \times 10000 \times 4.6 \: {m}^{2}10000×10000×4.6m

2

(1 km = 1000m)

=10 \times 10 \times 4.6 \: {km}^{2}10×10×4.6km

2

=

460 \: {km}^{2}460km
