You can put this solution on YOUR website!
Width = x
\n" ); document.write( "Length = 3x - 4
\n" ); document.write( "Perimeter = 2 * width + 2 * length
\n" ); document.write( "144 = 2(x) + 2(3x - 4)
\n" ); document.write( "144 = 2x + 6x - 8
\n" ); document.write( "144 = 8x - 8
\n" ); document.write( " 8x = 144 + 8
\n" ); document.write( " 8x = 152
\n" ); document.write( " x = 19
\n" ); document.write( "Width = 19m
\n" ); document.write( "Length = 53m
\n" ); document.write( "Hope this helps.
