Answer:
The length for 20 litre capacity will be 35.334 cm
Step-by-step explanation:
Given:
30 capacity litre corresponds to 53 cm
To Find :
20 liters.
Solution:
This representation is of double number line
i.e one line represents the capacity in litre and other length.
Now at 30 litre corresponds to 53 cm
So the ratio , 1 litre representation,
1:30/53
i.e. 53/30=1.7667
This ratio will be constant through out the line.
So for 20 litre it will be ,as
=20*(1.7667)
=35.334 cm
