The area of a pond on a map is 100 cm2 and the actual area of the pond is 10000 m2 . The scale of the map is

Question

A. 1 ∶ 100.

B. 1 ∶ 1000.

C. 1 ∶ 10000.

D. 1 ∶ 1000000.

Answer 1

Answer is B

Area of pond in map = 100 cm2 => Length of the pond in map = 10cm

Actual area of the pond = 10000 m2 => Actural length of the pond = 100m or 10000cm

So the ratio is given by

=> Length of the pond in map / Actual length in relief

=> 10/10000

=> 1/1000 or 1:1000
