1. A map drawn to a scale of 1 cm to 10 km, measures 24 cm by 18 cm. If the areas of land and water represented
are in the ratio of 7:2, find in square km, the land area represented.​

Answer 1

Answer:

33600 km²

Step-by-step explanation:

Scale 1 cm : 10 km

Means 1 cm cover 10 km on map

So,

24cm = 240 km

18cm=180km

Map area = 240*180

=43200km²

$\frac{land}{water} = \frac{7}{2} \\ part \: of \: land \: area = \frac{7}{9} \times 43200 \\ = 33600 \: {km}^{2}$

Sun of ratio 7+2 =9

Part of land will be 7/9 is use in above calculations
