Answer:
99cm^2
Step-by-step explanation:
When finding an area of a triangle, you multiply base times height and then divide by 2.
In this case,
Height:11
Base: 18
So then apply the formula:
[tex]\frac{11*18}{2}[/tex]
Solve (using a calculator lol)
We get 99
Don't forget units!
So the final answer is 99cm^2
