L=W+3
\n" ); document.write( "2(W+3)+2W=24
\n" ); document.write( "2W+6+2W=24
\n" ); document.write( "4W=24-6
\n" ); document.write( "4W=18
\n" ); document.write( "W=18/4
\n" ); document.write( "W=4.5 ANSWER FOR THE WIDTH.
\n" ); document.write( "L=4.5+3
\n" ); document.write( "L=7.5 ANSWER FOR THE LENGTH.
\n" ); document.write( "PROOF
\n" ); document.write( "2*4.5=2*7.5=24
