L=2W+4 IS THE LENGTH
\n" ); document.write( "W IS THE WIDTH
\n" ); document.write( "W(2W+4)=198
\n" ); document.write( "2W^2+4W-198=0
\n" ); document.write( "2(W^2+2W-99)=0
\n" ); document.write( "2(W+11)(W-9)=0
\n" ); document.write( "W-9=0
\n" ); document.write( "W=9 FEET IS THE WIDTH.
\n" ); document.write( "L=2*9+4=18+4=22 IS THE LENGTH.
\n" ); document.write( "PROOF
\n" ); document.write( "9*22=198
\n" ); document.write( "198=198\r
