H=B+3
\n" ); document.write( "A=BH/2
\n" ); document.write( "35=B(B+3)/2
\n" ); document.write( "35=(B^2+3B)/2
\n" ); document.write( "B^2+3B=35*2
\n" ); document.write( "B^2+3B=70
\n" ); document.write( "B^2+3B-70=0
\n" ); document.write( "(B+10)(B-7)=0
\n" ); document.write( "B-7=0
\n" ); document.write( "B=7 ANS. FOR THE BASE.
\n" ); document.write( "H=7+3=10 ANS. FOR THE HEIGHT.
\n" ); document.write( "PROOF:
\n" ); document.write( "35=7*10/2
\n" ); document.write( "35=70/2
\n" ); document.write( "35=35
