You can put this solution on YOUR website!
Width = x
\n" ); document.write( "Length = 3x
\n" ); document.write( "Perimeter = 2*length + 2*width
\n" ); document.write( "48 = 2(3x) + 2(x)
\n" ); document.write( "48 = 6x + 2x
\n" ); document.write( "8x = 48
\n" ); document.write( "x = 6
\n" ); document.write( "Width = 6m
\n" ); document.write( "Length = 18m.
\n" ); document.write( "Hope this helps.
