perimeter is 2L+2W so half perimeter (45) is L+W
\n" ); document.write( "width = x
\n" ); document.write( "length= x+5
\n" ); document.write( "their sum is 2x+5=45
\n" ); document.write( "2x=40
\n" ); document.write( "x=20 cm width
\n" ); document.write( "x+5=25 cm length
\n" ); document.write( "
\n" );
