Answer:
![A=906.9\ cm^2](https://tex.z-dn.net/?f=A%3D906.9%5C%20cm%5E2)
Step-by-step explanation:
A do-decagon is a polygon with 12 straight sides and 12 equal angles.
-The general formula for finding area of a do-decagon is given as:
![A=3(2+\sqrt{3})s^2](https://tex.z-dn.net/?f=A%3D3%282%2B%5Csqrt%7B3%7D%29s%5E2)
where s is the sides length.
-Given the sides dimension is 9cm, the area is calculated as;
![A=3(2+\sqrt{3})s^2\\\\=3(2+\sqrt{3})\times 9^2\\\\=906.8883462\approx906.9\ cm^2](https://tex.z-dn.net/?f=A%3D3%282%2B%5Csqrt%7B3%7D%29s%5E2%5C%5C%5C%5C%3D3%282%2B%5Csqrt%7B3%7D%29%5Ctimes%209%5E2%5C%5C%5C%5C%3D906.8883462%5Capprox906.9%5C%20cm%5E2)
Hence, the do-decagon's area is ![906.9\ cm^2](https://tex.z-dn.net/?f=906.9%5C%20cm%5E2)
