let the length of one leg be x cm
\n" ); document.write( "the other leg = 2x-1 cm
\n" ); document.write( "Hypotenuse = sqrt(13)
\n" ); document.write( "...
\n" ); document.write( "x^2+(2x-1)^2=(13)
\n" ); document.write( "x^2+4x^2-4x+1=13
\n" ); document.write( "5x^2-4x+1-13
\n" ); document.write( "5x^2-4x-12=0
\n" ); document.write( "5x^2-10x+6x-12=0
\n" ); document.write( "5x(x-2)+6(x-2)=0
\n" ); document.write( "(x-2)(5x+6)=0
\n" ); document.write( "x= 2
\n" ); document.write( "...
\n" ); document.write( "length of one leg = 2cm
\n" ); document.write( "other leg = 2x-1 = 3 cm
\n" ); document.write( "...
