What is the area of this triangle?

We know that :
Area of Triangle is given by [tex]\mathsf{: (\frac{1}{2} \times Base \times Height)}[/tex]
We can Notice from the Graph that :
Base of the Triangle = 8 units
Height of the Triangle = 3 units
[tex]\mathsf{\implies Area\;of\;the\;Triangle = \frac{1}{2}(3)(8)}[/tex]
[tex]\mathsf{\implies Area\;of\;the\;Triangle = 12\;units}[/tex]
