Final answer:
The area around the hairline is not called the perimeter; the perimeter refers to the outer edge or boundary of a hairstyle or the hairline.
Step-by-step explanation:
The area all around the hairline is not referred to as the perimeter, but rather as the hairline itself. The perimeter refers to the outer boundary or edge of an object or area. In the context of hair, the perimeter can be used to describe the outline of a hairstyle or the hairline of the scalp.
For example, if someone has a hairstyle with a shaved or tapered perimeter, it means that the hair is shorter or shaved around the edges of the head, creating a clear outline or boundary. On the other hand, if someone has a hairstyle with a natural or rounded perimeter, it means that the hairline has a softer, more gradual shape.
So, in summary, the area all around the hairline is not called the perimeter. The perimeter is actually used to describe the outer edge or boundary of a hairstyle or the hairline of the scalp.
