What is the number of square units in the area of the triangle whose vertices are points (2,0), (6,0), (8,5)
Answers: 2
is given by :-![A=\dfrac{1}{2}[x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)]](/tpl/images/0464/0878/c6de3.png)
![A=\dfrac{1}{2}[(2)((0)-(5))+(6)((5)-(0))+(8)((0)-(0))\\\\\Rightarrow A=\dfrac{1}{2}[20]\\\\\Rightarrow A=10\text{ square units}](/tpl/images/0464/0878/30955.png)
