Question

a map is drawn in the scale of 1:500000. the area of a pond on the actual ground is 100km^2. find the area on the map in square centimetres that represents the pond

Answer 1

2 000 000
`cm^(2)`

Explanation:

100
`km^(2)` = 1 000 000 000 000
`cm^(2)`

the scale of 1:500000 means that 1 cm in the map represents 500000 cm in reality

So on the map this pond's area would be

`(1 000 000 000 000)/(500000)` = 2 000 000
`cm^(2)`
