Answer:
Area is 321.6 square inches.
Explanation:
A regular polygon with 16 sides is a Regular Hexadecagon. Regular means all sides are equal dimension. See image attached.
Side length is 4 inches.
side length=s=4 inches
- You need to calculate the apothem.
Apothem=s*2.51367
Apothem=10.054
2. You can use the formula to calculate de area of an hexadecagon:
![A=(Perimeter*Apothem)/(2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/n3ij774cvueyz3c1a2vxsoakfr04o0wcvf.png)
Perimeter=16 sides*4inches
Perimeter= 64 inches
![A=(64*10.054)/(2)](https://img.qammunity.org/2020/formulas/mathematics/college/k9vnq39a2nb6ejnyscu8ykwrbp5na5h3ir.png)
