H=B+6
\n" ); document.write( "A=BH/2
\n" ); document.write( "13.5=B(B+6)/2
\n" ); document.write( "13.5=(B^2+6B)/2
\n" ); document.write( "2*13.5=B^2+6B
\n" ); document.write( "B^2+6B-27=0
\n" ); document.write( "(B+9)(B-3)=0
\n" ); document.write( "B-3=0
\n" ); document.write( "B=3 FOR THE BASE
\n" ); document.write( "3+6=9 FOR THE HEIGHT.
\n" ); document.write( "PROOF:
\n" ); document.write( "13.5=(3*9)/2
\n" ); document.write( "13.5=27/2
