Answer:
<u>Applying Heron's Formula</u>
![s=\frac{2.89+4.3+6.81}{2}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B2.89%2B4.3%2B6.81%7D%7B2%7D)
![s_1=7](https://tex.z-dn.net/?f=s_1%3D7)
![A_1=\sqrt{7(7-2.89)(7-4.3)(7-6.81)}](https://tex.z-dn.net/?f=A_1%3D%5Csqrt%7B7%287-2.89%29%287-4.3%29%287-6.81%29%7D)
![A_1=10.56](https://tex.z-dn.net/?f=A_1%3D10.56)

![s_2=11.49](https://tex.z-dn.net/?f=s_2%3D11.49)
![A_2=\sqrt{11.49(11.49-6.81)(11.49-8.59)(11.49-7.59)}](https://tex.z-dn.net/?f=A_2%3D%5Csqrt%7B11.49%2811.49-6.81%29%2811.49-8.59%29%2811.49-7.59%29%7D)
