Length = x
\n" ); document.write( "Width = 1 1/2 x = 3/2x
\n" ); document.write( "Perimeter = 90
\n" ); document.write( "Perimeter = 2 X length + 2 X width
\n" ); document.write( "= 2x + 2 X 3/2x
\n" ); document.write( "= 2x + 3x
\n" ); document.write( "= 5x
\n" ); document.write( "5x = 90
\n" ); document.write( "x = 90/5 = 18
\n" ); document.write( "Length = 18
\n" ); document.write( "Width = 3/2 X 18 = 27
\n" ); document.write( "
\n" );
