let the sides be a,b & c with a being the shortest and c the hypotenuse(longest)\r
\n" ); document.write( "\n" ); document.write( "the are of the triangle will be 1/2*a*b (half*base*height)\r
\n" ); document.write( "\n" ); document.write( "given \r
\n" ); document.write( "\n" ); document.write( "The length of the shortest side is equal to one-fifth of the sum of the lengths of the other two sides\r
\n" ); document.write( "\n" ); document.write( "so a=1/5 *(b+c)\r
\n" ); document.write( "\n" ); document.write( "=> 5a=b+c ------------------ 1\r
\n" ); document.write( "\n" ); document.write( "and perimeter = 2010 units\r
\n" ); document.write( "\n" ); document.write( "so a+b+c = 2010\r
\n" ); document.write( "\n" ); document.write( "but from 1 \r
\n" ); document.write( "\n" ); document.write( "we get a+5a=2010\r
\n" ); document.write( "\n" ); document.write( "so 6a=2010\r
\n" ); document.write( "\n" ); document.write( "so a=335\r
\n" ); document.write( "\n" ); document.write( "and b+c=5a=1675\r
\n" ); document.write( "\n" ); document.write( "now in a right triangle fro Pythagoras theorem we have\r
\n" ); document.write( "\n" ); document.write( "c^2 = a^2+b^2\r
\n" ); document.write( "\n" ); document.write( "=> c^2-b^2=a^2
\n" ); document.write( "
\n" ); document.write( "=> c^2-b^2=335*335\r
\n" ); document.write( "\n" ); document.write( "=> (c-b)(c+b)=335*335\r
\n" ); document.write( "\n" ); document.write( "but c+b = 1675\r
\n" ); document.write( "\n" ); document.write( "so (c-b)*1675=335*335\r
\n" ); document.write( "\n" ); document.write( "so c-b = 67
\n" ); document.write( " c+b= 1675\r
\n" ); document.write( "\n" ); document.write( "subtracting the above two we get \r
\n" ); document.write( "\n" ); document.write( "2b=1608 so b= 804\r
\n" ); document.write( "\n" ); document.write( "thus area=1/2 * 335 * 804\r
\n" ); document.write( "\n" ); document.write( "therefore area of the triangle=134670 sq. units
\n" ); document.write( "
\n" );
