The area of the triangle is 3200 square mm.The height of the triangle is ___ mm.

Since the area of the triangle is 3200 square mm and the base length is 80 mm, then we can use the formula for the area using this information:
[tex]\begin{gathered} A=3200\operatorname{mm}^2 \\ b=80\operatorname{mm} \\ A=\frac{b\cdot h}{2} \\ \Rightarrow3200=\frac{80\cdot h}{2} \\ \Rightarrow3200=40\cdot h \\ \Rightarrow h=\frac{3200}{40}=80 \\ h=80\operatorname{mm} \end{gathered}[/tex]therefore, the height of the triangle is 80 mm
Answer: The height of the triangle is 80 mm
