The figure above represents one of two pairs of identical support legs that will be part of the frame of a swing set, which is to be constructed on level ground using metal pipe. Each pair of support legs will have a horizontal bar 1.5 meters above ground level, and the triangle formed by the bar and support legs will be equilateral. Each support leg will extend below ground level by 0.5 meter. The frame will be completed by a horizontal bar, 5 meters in length and 3 meters above ground level, that will connect the tops of the two pairs of support legs. Approximately what is the total length, in meters, of the metal pipe needed to construct the entire frame?

Right answer is D
