Answer 2

Given:

20 cm

To find:

The measure of 20 cm in m and km

Solution:

The required values are 0.2m and 0.0002 km.

We can obtain the required values by dividing the given measure by 100 and 1/1,00,000.

So, the given measure=20 cm

The measure in metres=Measure in cm/100

=20/100

=0.2 m

The measure in km=Measure in cm/ 1,00,000

=20/1,00,000

=0.0002 km

Therefore, the required values are 0.2m and 0.0002 km.
