14. 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:

area of length represented in the map is 33,600sq./ km

Step-by-step explanation:

given : nap drawn 1 cm to 10 km.

length = 24 , and width = 18

So, the measurement of the given area in real,

length = 24 x 10km

=240km

width = 18 x 10km

= 180km

So, area measured = length x width

= 240km x 180 km

= 43,200km

Since, the ratio of the land and water = 7:2

7x + 2x = 43,200

9x = 43,200

x = 43,200/9

x = 4,800km

Hence, the area of land = 7x

= 7 x 4,800km

= 33,600Sq./km
