L=W+3
\n" ); document.write( "LW=40
\n" ); document.write( "(W+3)W=40
\n" ); document.write( "W^2+3W-40=0
\n" ); document.write( "(W+8)(W-5)=0
\n" ); document.write( "W-5=0
\n" ); document.write( "W=5 CM. FOR THE WIDTH
\n" ); document.write( "L=5+3=8 CM FOR THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "5*8=40
\n" ); document.write( "40=40
