Given:
The figured of an obtuse triangle.
To find:
The area of the triangle.
Solution:
We know that, the area of a triangle is
[tex]Area=\dfrac{1}{2}\times Base\times height[/tex]
From the given figure it is clear that the height of the triangle is 9 and the base is 22. So, the area of the triangle is
[tex]Area=\dfrac{1}{2}\times 22\times 9[/tex]
[tex]Area=11\times 9[/tex]
[tex]Area=99[/tex]
The area of the given triangle is 99 sq. units.
Therefore, the correct option is C.
