Hi there,
\n" ); document.write( "Make length = x
\n" ); document.write( "width = x/2 - 2
\n" ); document.write( "Perimeter = 2(length) + 2(width)
\n" ); document.write( "86 = 2(x) + 2(x/2 - 2)
\n" ); document.write( "86 = 2x + x - 4
\n" ); document.write( "Collect like terms:
\n" ); document.write( "2x + x = 86 + 4
\n" ); document.write( "3x = 90
\n" ); document.write( "x = 30
\n" ); document.write( "Length = 30cm
\n" ); document.write( "Width = 13cm
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "
\n" );
