\n" ); document.write( "Area of a triangle with sides: 12cm, 13cm and 5cm
\n" ); document.write( "*Note: Heron's Equation will find the area of a triangle when 3 sides are given
\n" ); document.write( "
\n" ); document.write( "A=\"sqrt%28s%28s-a%29%28s-b%29%28s-c%29%29\" where s is the semi-perimeter in this case s =30/2cm = 15cm
\n" ); document.write( "A=\"sqrt%2815%2815-12%29%2815-13%29%2815-5%29%29\"
\n" ); document.write( "A=\"sqrt%2815%283%29%282%29%2810%29%29\"
\n" ); document.write( "A=\"sqrt%28900%29\"
\n" ); document.write( "A= 30cm^2 \n" ); document.write( "
