Answer :
Given:
A triangular pennant has an area of 432 sq cm
Required:
We need to find the height if base is 36 cm
Explanation:
Area of triangle is
[tex]A=\frac{1}{2}hb[/tex]where h is height and b is base
base b is 36 cm
and area A is 432 sq cm
Substitute all the values
[tex]\begin{gathered} 432=\frac{1}{2}*36h \\ \\ 864=36h \\ h=\frac{864}{32}=24\text{ cm} \end{gathered}[/tex]Final answer:
The height h is 24 cm
