let height be x
\n" ); document.write( "the base is 6cm less than height therefore base b =x - 6\r
\n" ); document.write( "\n" ); document.write( "area =(1/2)*b*h = 36
\n" ); document.write( "b*h = 72
\n" ); document.write( "x*(x-6)=72
\n" ); document.write( "x^2-6x-72=0
\n" ); document.write( "(x-12)(x+6)=0
\n" ); document.write( "x= 12 or -6
\n" ); document.write( "but height cannot be negative so x = 12cm and base = 12-6=6cm
\n" ); document.write( "
\n" ); document.write( "
\n" );
