\n" );
document.write( "Find the area of the triangle.
\n" );
document.write( "A = (1/2)b*h  where h = \"sqrt%2825-%282.5%29%5E2%29\" using the Pythagorean Theorem
\n" );
document.write( "     A = (1/2)* 5in *\"sqrt%2825-%282.5%29%5E2%29\" = 10.8253in^2\r
\n" );
document.write( "\n" );
document.write( "Checking our answer using the Heron's Equation:
\n" );
document.write( "\"sqrt%28s%28s-a%29%28s-b%29%28s-c%29%29\" where a,b,c are the lengths of the sides and s is the semi-perimeter
\n" );
document.write( "\"sqrt%287.5%282.5%29%5E3%29\" = 10.8253in^2\r
