Answer: [tex]54cm^{2}[/tex]
The area of a triangle is given by:
[tex]A_{triangle}=\frac{(b)(h)}{2}[/tex]
Where:
[tex]b=9cm[/tex] is the base of this right triangle
[tex]h=12cm[/tex] is the height of the triangle
Substituting the known values:
[tex]A_{triangle}=\frac{(9cm)(12cm)}{2}[/tex]
Finally, the area of this triangle is:
[tex]A_{triangle}=54cm^{2}[/tex]
