You can put this solution on YOUR website!
Width = x
\n" ); document.write( "Length = 12 + x
\n" ); document.write( "Perimeter = 2*width + 2*length
\n" ); document.write( "60 = 2(x) + 2(12 + x)
\n" ); document.write( "60 = 2x + 24 + 2x
\n" ); document.write( "4x = 60 - 24
\n" ); document.write( "4x = 36
\n" ); document.write( "x = 9cm
\n" ); document.write( "Width = 9cm
\n" ); document.write( "Length = 21cm.
