A tourist visiting three iconic Washington, D.C. landmarks wants to know the order of the sides (distances) from shortest to longest. Based on the given measurements:
These distances likely represent the lengths of the building façades or specific sides facing a common reference point (e.g., the National Mall). The White House's north façade (Pennsylvania Avenue) is approximately 160 ft (49 m), but the given figure of 160 m may refer to a different dimension or a hypothetical problem setup. Similarly, the Lincoln Memorial's colonnade width is ~60 m, and the National Museum of Natural History's Mall façade is ~200 m. The provided numbers (160 m, 180 m, 240 m) are used here as stated for the ordering exercise.
In reality, the walking distances between these sites on the National Mall are:
But for the specific side-length comparison given: White House (160 m) < Lincoln Memorial (180 m) < National Museum of History (240 m).
