![**Question:**
What is the perimeter of the shape?
**Diagram Description:**
The image shows a shaded star with equal sides. Each side of the star measures 2 mm.
**Multiple Choice Options:**
A. 2 mm
B. 4 mm
C. 10 mm
D. 20 mm
**Explanation:**
To calculate the perimeter of the star, count the number of sides and multiply by the length of each side. Since a star has 10 equal-length sides (5 points with 2 sides each), the perimeter is calculated as:
\[ \text{Perimeter} = 10 \times 2 \, \text{mm} = 20 \, \text{mm} \]
**Correct Answer:**
D. 20 mm](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F33ca75ea-86eb-4601-9103-178c62467fbe%2F7ff03e1e-98ff-4907-9423-e8de7726d6f4%2Fzulo8m_processed.jpeg&w=3840&q=75)
