Answer :
Answer: A=27 mm²
Step-by-step explanation:
To find the area of a triangle, the formula is [tex]A=\frac{1}{2}bh[/tex]. Since we know the base and height, we can directly plug them into the formula.
[tex]A=\frac{1}{2}(6)(9)[/tex] [divide]
[tex]A=3(9)[/tex] [multiply]
[tex]A=27 mm^2[/tex]
The area of the triangle is A=27 mm².
