AREA=BH/2
\n" ); document.write( "90=(H+11)H/2
\n" ); document.write( "90=(H^2+11H)/2
\n" ); document.write( "H^2+11H=90*2
\n" ); document.write( "H^2+11H-180=0
\n" ); document.write( "(H+20)(H-9)=0
\n" ); document.write( "H-9=0
\n" ); document.write( "H=9 ANS. FOR THE HEIGHT.
\n" ); document.write( "9+11=20 ANS. FOR THE BASE.
\n" ); document.write( "PROOF:
\n" ); document.write( "90=9*20/2
\n" ); document.write( "90=180/2
\n" ); document.write( "90=90
\n" ); document.write( "
