The scale of a map is 1:250000. On the map a large forest has an area of 6cm². Calculate the actual area of the forest. Give you
1 answer:
The distance on map exists 32 cm and actual area exists 37.5 km².
<h3>How to estimate the actual area of the forest in square kilometers?</h3>
Given: Scale of the map exists at 1:250000.
(a) Distance between two cities = 80 km
= 80000 m
= 8000000 cm
Distance on map = 8000000 1/ 250000
= 32 cm
(b) Area of map = 6 cm²
Actual area = cm²
cm²
= 37.5 km²
Therefore, the distance on map exists 32 cm and actual area exists 37.5 km².
