document.write( "Let consider this right angled triangle with vertices (0,-4), (0.0), and (1,0).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Its legs have the length 4 and 1; its hypotenuse is  \"sqrt%284%5E2%2B1%5E1%29\" = \"sqrt%2817%29\" long.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "We can easy find the height \"h\" (the altitude) of this triangle, drawn to hypotenuse.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the area consideration, we have this equation\r\n" );

document.write( "    \"%284%2A1%29%2F2\" = \"%281%2F2%29%2Asqrt%2817%29%2Ah\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It gives  h = \"4%2Fsqrt%2817%29\" = 0.970143.\r\n" );

document.write( "\r\n" );
document.write( "So, it is not 1 unit, as you see.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that the legs of the triangle should be  \"sqrt%2817%29%2F4\"  as long, as 1 unit and 4 units of the original triangle.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the area of the seeking triangle is  \"%281%2F2%29%2A%28sqrt%2817%29%2F4%29%2A%28%284%2Asqrt%2817%29%29%2F4%29%29\" = \"%281%2F2%29%2A%2817%2F4%29\" = \"17%2F8\".    ANSWER\r\n" );
