Question

A map is drawn to a scale of 1:10 000. Find:
a) the distance between two railway stations
which appear on the map 24 cm apart.
b) the area, in square kilometres, of a lake
which has an area of 100 cm² on the map.

Answer 1

Answer:

50 km

Explanation:

So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by

2.5

1

. Then, 20 x 2.5=50. So the answer is 50 km

Answer 2

Answer:

Scale:- (Both are in cm)

1   : 10,000

24: x

(Now we will cross multiply)

1*x = 24 * 10,000

x = 240,000cm or 2.4 km
