Answer:
The area of triangle is 48.
Step-by-step explanation:
Given:
The vertices of triangle are (0,0),(12,0),(2,8).
Now, to find the area of triangle.
So, the coordinates of triangle are:
.
Now, to get the area of triangle we put formula:
![Area\,of\,triangle\,=\,\frac{1}{2}\left|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)\right|](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B1%7D%7B2%7D%5Cleft%7Cx_1%28y_2-y_3%29%2Bx_2%28y_3-y_1%29%2Bx_3%28y_1-y_2%29%5Cright%7C)

![Area\,of\,triangle\,=\,\frac{1}{2}\left|0\times -8+12\times 8+2\times 0\right|](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B1%7D%7B2%7D%5Cleft%7C0%5Ctimes%20-8%2B12%5Ctimes%208%2B2%5Ctimes%200%5Cright%7C)

![Area\,of\,triangle\,=\,\frac{1}{2}\left|96\right|](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B1%7D%7B2%7D%5Cleft%7C96%5Cright%7C)
![Area\,of\,triangle\,=\,\frac{1}{2}\times 96](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B1%7D%7B2%7D%5Ctimes%2096)
![Area\,of\,triangle\,=\,\frac{96}{2}](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B96%7D%7B2%7D)
![Area\,of\,triangle\,=\,48.](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C48.)
Therefore, the area of triangle is 48.
