The base of the prism is the triangle.
The area of the triangle (B) is:
[tex]B=\frac{b\cdot h}{2}[/tex]
where:
b is the base of the triangle = 7.2.
h = height of the triangle.
Substituting the values:
[tex]\begin{gathered} B=\frac{7.2}{2}\cdot h \\ B=3.6\cdot h \end{gathered}[/tex]
Answer:
[tex]B=3.6\cdot h[/tex]
