I want to know the answer to the following question:
When was the IFAB's decision on the fixed size of the pitch become implemented?
All the background I'm provided with is that "The length of the pitch for international adult matches is in the range of 100–110 m (110–120 yd) and the width is in the range of 64–75 m (70–80 yd).". Is that enough to answer the question?
