The length of

The given information seems to represent a code or pattern. Let's analyze it:
- 20 corresponds to G
- 19 corresponds to GH
- 39 corresponds to JK
It appears that the number is associated with the position of the letters in the alphabet.
- For \(G\), the 7th letter of the alphabet, 20 - 7 = 13 .
- For \(H\), the 8th letter of the alphabet, 19 - 8 = 11 .
- For \(J\), the 10th letter of the alphabet, 39 - 10 = 29 .
Now, let's find the corresponding value for L , the 12th letter of the alphabet:
39 - 12 = 27
So, L corresponds to 27.
Therefore, the length of
