What is the shape of a tract of land placed on a navigable stream?

The shape of a tract of land placed on a navigable stream is determined by the principles of property law and surveying. When considering land adjacent to a navigable stream, the typical understanding is that the ownership extends to the midpoint of the navigable waterway, creating a scenario where the land is shaped in a manner that accounts for both the land and the waterway.

The correct answer is that the shape of the tract of land is half the square of the area on the stream. This aligns with the concept that when land is partially defined by its relationship to a navigable body of water, the usable area can indeed be thought of in such a geometrical manner, particularly in legal contexts concerning riparian rights and claims. The calculation essentially engages with the areas that can be defined legally as being part of the land bordering the water, where the 'half' signifies the delineation along the navigable portion rather than an arbitrary boundary disconnected from the water.

Other options suggest geometric shapes that do not accurately reflect the interaction between land and navigable waters, thus failing to uphold the principles of property rights adjacent to such areas. For example, a square or rectangular shape does not account for the natural and legal aspects of land bordering a stream, and a curved
