W=L+3
\n" ); document.write( "LW=550
\n" ); document.write( "L(L+3)=550
\n" ); document.write( "L^2+3L=550
\n" ); document.write( "L^2+3L-550=0
\n" ); document.write( "(L+25)(L-22)=0
\n" ); document.write( "LL-22=0
\n" ); document.write( "L=22 ANS. FOR THE LENGTH.
\n" ); document.write( "W=22+3=25 ANS. FOR THE WIDTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "22*25=550
\n" ); document.write( "550=550
\n" ); document.write( "
