You can put this solution on YOUR website!
Width = x
\n" ); document.write( "Length = 2x
\n" ); document.write( "Perimeter = 2*Length + 2*Width
\n" ); document.write( "30 = 2*2x + 2*x
\n" ); document.write( "30 = 4x + 2x
\n" ); document.write( "6x = 30
\n" ); document.write( "x = 5
\n" ); document.write( "Width = 5 units
\n" ); document.write( "Length = 10 units
\n" ); document.write( "Hope this helps.
