Answer:
135 square centimeters.
Step-by-step explanation:
The area of a triangle is given by the formula:
[tex]A=\frac{1}{2}bh[/tex]
Where b is the base length and h is the length of the vertical height.
From the triangle, we can see that the base is 18 and the vertical height is 15. Thus:
[tex]A=\frac{1}{2}(18)(15)[/tex]
Multiply:
[tex]A=(9)(15)\\A=135\text{ cm}^2[/tex]
The area of the triangle is 135 square centimeters.
