Answer 1

Given:

A triangular pennant has an area of 432 sq cm

Required:

We need to find the height if base is 36 cm

Step-by-step explanation:

Area of triangle is

`A=(1)/(2)hb`

where h is height and b is base

base b is 36 cm

and area A is 432 sq cm

Substitute all the values

`\begin{gathered} 432=(1)/(2)*36h \\ \\ 864=36h \\ h=(864)/(32)=24\text{ cm} \end{gathered}`

Final answer:

The height h is 24 cm
