[DoubleUp]

A rectangular fence is to be constucted against the side of a building that will act as one side of the fence. The fenced area is to be 2400 sq units and the long side of the fence is to be 3 times the short side. Determine the length of the fence. Draw a diagram that illustrates the fenced area.
