Question

Find area of a triangle whose perimeter is 180cm and its two side are 80cm and 18cm calculate the altitude of triangle corresponding to its shortest distance

Answer 1

Let , the sides of triangle be a, b, and c.
We have, a+b+c=180
and, a is 80 and b is 18.
so, c will be 180-(80+18) = 82
So, sides are 80, 82 and 18.
Now, use heron's formula to calculate the area.
Accordingly, computerise the required altitude.
