Answer:
99cm^2
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:
![(11*18)/(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/sg73p7m5xh70qoj6xs3wejdee2doklfg09.png)
Solve (using a calculator lol)
We get 99
Don't forget units!
So the final answer is 99cm^2
