Question

The area of a triangle measures 128 centimeters squared with a base length of 14 centimeters. Find the length of the altitude. (I asked my math teacher about this, but she only said that you don't draw the altitude to the base).​

Answer 1

The altitude is
`18(2)/(7)cm`

Explanation:

The area of a triangle is calculated using the formula;

`Area=(1)/(2)bh`

Where Area=128 centimeters square and
`b=14cm` and
`h` is the altitude.

`128=(1)/(2)(14)(h)`

`128=7h`

`h=(128)/(7)`

`h=18(2)/(7)cm`
