I want to know the answer to the following question:
To what measurement, in cm, did the wingspans of giant dragonfly-like forms reach?
All the background I'm provided with is that "During this era, some giant dragonfly-like forms reached wingspans of 55 to 70 cm (22 to 28 in), making them far larger than any living insect.". Is that enough to answer the question?
Answer: yes
