Final answer:
When the scale on a map changes from representing 200 ft to 150 ft, the size of Washington Park will appear larger.
Step-by-step explanation:
When the exact same-sized bar represents a smaller distance, the object being represented will appear larger. This is because the size of the map has remained the same, but the scale has changed. In this case, the new scale of 150 feet means that each inch on the map now represents a larger distance than before.
Therefore, Washington Park will appear larger under the 150 ft scale compared to the 200 ft scale.
