Question

The scale of a map is 1 cm : 3 metres.
The distance on the map between two towns is 7cm.
What is the actual length of the two towns?​

Answer 1

Answer:

$\Large{\boxed{\red{\underline{21 Meters}}}}$

Step-by-step explanation:

On map, a simple small unit is choosen, so that big units can be expressed by small units.

The scale of the map is 1 cm = 3 meters, So, every 1 cm on map is 300 cm or 3 meters.

Given, is the distance on the map between two towns is 7 cm. Means 7 cm is the smaller unit.

(We have, 1 cm = 3 m)

So, by solving we get,

$\boxed{\red{\underline{7 \times 3 = 21}}}$

So, the answer is $\boxed{\red{\underline{21 Meters}}}$

Meter is the bigger unit so after solving we choose bigger unit in the answer.
