Consider the statement: Ratio of breadth and length of a hall is 2 : 5. Complete the following table that shows some possible breadths and lengths of the hall.

Explanation

Here, breadth of the hall(b)/length of hall(l) = 2/5

`b/l = 2/5`

`b/l = (2**10)/(5**10) = 20/50`

So, in the first blank, it will be `20`.

`b/l = (2**20)/(5**20) = 40/100`

So, in the first blank, it will be `100`.
