What is wrong with this program?

I don't understand what is wrong with this program. It gives an error:
'findarea' undefined local variable or method 'area_of_triangle'
Both 'findarea' and 'area_of_triangle' are clearly defined.

Prateek,

You post alot of basic troubleshooting questions on the list. This
really is something you need to learn to do on your own when
programming, as no one gets their code right the first time through
the keyboard.

But for this, a simple Ctrl+F through your own code will give you the
answer.

Hi
   two errors there

1 area_of_triange=Math.sqrt(s*(s-side_a)*(s-side_b)*(s-side_c))
    spelling mistake in area_of_triange
2 return area
    area is not defined

Also, seems to be homework based on the filename.

One of my friends during conversation:

what i have learned from my time at hms both as a tech and as a mentor
that getting answers is a drug. you get addicted to it. if you find
some venue through which you happen to get a bunch of answers, be it a
forum or list or nate coffield, you will abuse it until it turns on you

Hey,

There are couple of things to be mended in the function "findarea".

They are

(i) "area_of_segment=(4.0/3)*area_of_triangle" But in the prev line,
you have declared the variable as "area_of_triange". "L(l) is
missing."

(ii) You're returning the variable "area" from the function to the
main block. But there is no such variable in the function. Guess it
has to be "area_of_segment".

This should work now.
