A map is drawn to a scale of 1 cm to 250 cm.

Darina [25.2K]

Answer:

0.0015 km².

Step-by-step explanation:

It is given that a map is drawn to a scale of 1 cm to 250 cm.

$1\ cm\times 1\ cm=250\ cm\times 250\ cm$

$1\ cm^2=62500\ cm^2$

It is given that an airport has an area of 240 cm² on the map. So, its actual area is

$Area=240\times 62500\ cm^2$

$Area=15000000\ cm^2$

$Area=\dfrac{15000000}{10000000000}\ km^2$

$Area=0.0015\ cm^2$ $[\because 1\ km^2=10000000000\ cm^2]$

Therefore, the area of airport is 0.0015 km².
