The area of a triangle is given by
[tex]A=\frac{1}{2}\cdot b\cdot h[/tex]
Where b is the base and h is the height of the triangle.
Let us substitute the given values of base and height into the above formula
[tex]\begin{gathered} A=\frac{1}{2}\cdot b\cdot h \\ A=\frac{1}{2}\cdot9\cdot7 \\ A=\frac{63}{2} \\ A=31.5 \end{gathered}[/tex]
Therefore, the area of the triangle is 31.5 square units.
