The area of a regular decagon will be 492 inch³. The area of the decagon is the product of the perimeter of the decagon and apothem.
What is a decagon?
Decagon is a geometrical figure with the side equal to 10. The length of the each side is same arranged around a circle.
The regular decagon is found by the formula below;
Area of decagon = perimeter of decagon × apothem
The perimeter of the decagon is the sum of its all sides;
[tex]\rm P = 10 \times 8 \\\\ P= 80 \ yards[/tex]
The area of the regular decagon is;
[tex]\rm A = \frac{1}{2} \times 80 \times 12.3 \\\\\ A = 492 \ inch^2[/tex]
Hence the area of a regular decagon will be 492 inch².
