Answer:
The altitude is [tex]18\frac{2}{7}cm[/tex]
Step-by-step explanation:
The area of a triangle is calculated using the formula;
[tex]Area=\frac{1}{2}bh[/tex]
Where Area=128 centimeters square and [tex]b=14cm[/tex] and [tex]h[/tex] is the altitude.
[tex]128=\frac{1}{2}(14)(h)[/tex]
[tex]128=7h[/tex]
[tex]h=\frac{128}{7}[/tex]
[tex]h=18\frac{2}{7}cm[/tex]
