 		Hi i know im new to this and dont have much posts but im learning trying to home teach my self C#
and i have a problem if this code looks right?
its an application that reads the length of the triangle sides from a user using the herons formula which is s=(a+ b+c) /2.0d;
area= Math.Sqrt(s*(s-a)*(s-b)*(s-c));
in which s represents half of the perimeter of the trangle a,b,c represents the length of the three sides, how do i print the areas to three decimal places? and does the code look good so far?
im using microsoft visual c#2010 express

 		I've had a quick look and your code looks fine to me. You can use string formatting to get the 3 decimals you want:
