Question

A map is drawn to a scale of 1:1000000
A forest on the map has an area of 4.6cm²
Calculate the actual area of the forest in square kilometers

Answer 1

Representative Factor - 1:1000000
This means 1 cm on the map represents 1000000 cm on the actual ground

Area of forest on map =
$4.6 \: {cm}^{2}$

$1 \: {cm}^{2}$ on map represents
$1000000 \times 1000000 \: {cm}^{2}$ on actual ground

Area of forest :

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

(1 m = 100 cm)
=$10000 \times 10000 \times 4.6 \: {m}^{2}$

(1 km = 1000m)
=$10 \times 10 \times 4.6 \: {km}^{2}$

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