Let the base be 2x.
\n" ); document.write( "Then the height is x.
\n" ); document.write( "Area of the triangle=1/2*base*height
\n" ); document.write( "Plugging in the values we get,
\n" ); document.write( "81=1/2*x*2x
\n" ); document.write( "x^2=81
\n" ); document.write( "x=9 inches
\n" ); document.write( "The height of the triangle is 9 inches.
\n" ); document.write( "The base of the triangle is 18 inches.
\n" ); document.write( "
\n" );
