Answer:
9%
both lower extremities
Step-by-step explanation:
What percentage of the daughter's body received first-degree burns?
We are told that the daughter has first-degree burns on her head and neck. I'm assuming the daughter is an adult, in which case that accounts for 9% of her body.
What part of the daughter's body has burns to both the dermis and epidermis?
This is asking for burns through two layers of tissue, which would mean second-degree burns. (Second-degree means two layers of tissue are burned: the dermis and epidermis.) So the answer is both lower extremities.
