\n" ); document.write( "The sides of a triangle are in the ratio 5:12:13 and its perimeter is 150 m. Find the area of triangle.
\n" ); document.write( "

A triangle with sides 5, 12, and 13 represents a special right triangle. That's because 
\n" );
document.write( "To determine the length of each side, we let the multiplicative factor for the sides, be x
\n" );
document.write( "Therefore, the sides are: 5x, 12x, and 13x
\n" );
document.write( "With the perimeter being 150, we get: 5x + 12x + 13x = 150
\n" );
document.write( "30x = 150 
\n" );
document.write( "x = , or 5\r
\n" );
document.write( "\n" );
document.write( "We now have the sides as:
\n" );
document.write( "5(5), or  25 m
\n" );
document.write( "12(5), or 60 m
\n" );
document.write( "13(5), or 65 m\r
\n" );
document.write( "\n" );
document.write( "Obviously, the 2 shorter sides are the legs, with either leg being the altitude
\n" );
document.write( "Area:  = , or  \n" );
