The area of the pentagon is 19 square units
The coordinates of the pentagon are given as:
![T = (1, 8)](https://tex.z-dn.net/?f=T%20%3D%20%281%2C%208%29)
![E =(3, 8)](https://tex.z-dn.net/?f=E%20%3D%283%2C%208%29)
![X =(6, 2)](https://tex.z-dn.net/?f=X%20%3D%286%2C%202%29)
![A=(3, 2)](https://tex.z-dn.net/?f=A%3D%283%2C%202%29)
![S = (1, 4)](https://tex.z-dn.net/?f=S%20%3D%20%281%2C%204%29)
The area of the pentagon is then calculated using:
![Area = \frac 12|(x_1y_2+x_2y_3+x_3y_4+x_4y_5+x_5y_1) -(y_1x_2+y_2x_3+y_3x_4+y_4x_5+y_5x_1)|](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%2012%7C%28x_1y_2%2Bx_2y_3%2Bx_3y_4%2Bx_4y_5%2Bx_5y_1%29%20-%28y_1x_2%2By_2x_3%2By_3x_4%2By_4x_5%2By_5x_1%29%7C)
So, we have:
![Area = \frac 12|(1 \times 8 +3 \times 2+6\times2+3 \times 4 + 1 \times 8) -(8\times3+8\times6+2\times3+2\times1+4\times1)|](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%2012%7C%281%20%5Ctimes%208%20%2B3%20%5Ctimes%202%2B6%5Ctimes2%2B3%20%5Ctimes%204%20%2B%201%20%5Ctimes%208%29%20-%288%5Ctimes3%2B8%5Ctimes6%2B2%5Ctimes3%2B2%5Ctimes1%2B4%5Ctimes1%29%7C)
Simplify the expressions in both brackets
![Area = \frac 12|46 -84|](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%2012%7C46%20-84%7C)
![Area = \frac 12|-38|](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%2012%7C-38%7C)
Remove absolute bracket
![Area = \frac 12 \times 38](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%2012%20%5Ctimes%2038)
![Area = 19](https://tex.z-dn.net/?f=Area%20%3D%2019)
Hence, the area of the pentagon is 19 square units
