let the width be x
\n" ); document.write( "then length is x+3
\n" ); document.write( "24=2(x+3)+2x
\n" ); document.write( "24=2x+6+2x
\n" ); document.write( "24=4x+6
\n" ); document.write( "18=4x
\n" ); document.write( "4.5=x
\n" ); document.write( "so width is 4.5
\n" ); document.write( "then length is 4.5+3=7.5
\n" ); document.write( "
\n" );
