The area of the regular nonagon is 270 sq cm.
Step-by-step explanation:
Given,
Each side of a regular nonagon (b) = 10 cm
The length of apothem (h) = 6 cm.
To find the area of the nonagon.
Formula
The area of a nonagon with b as each side and h as apothem is = 9(
bh)
Now,
Putting the value of h and b we get,
Area = 9(
×10×6) sq cm = 270 sq cm
Hence, the area is 270 sq cm.
