Question

On Map 1, which has a scale of 1:25000, length of road is 5.5cm and the area of a park is 1.4cm2

On Map 2, which has a scale of 1: n, the area of the same park is 35 cm2.
Find the value of n.

Answer 1

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
