Answer:
When s=2, A=24
Step-by-step explanation:
We are given the formula 
We need to solve and find value of A , when s=2
So, putting value of s in the given formula we can find value of A
The formula given is:

So, by putting s= 2, We get A=24
We know that, 1 litre = 1000 ml
Then, 2 litres = 2000 ml
Hence, the required ratio of 1000 ml to 2000 ml be
= 1000 : 2000
= 1 : 2
