To find the missing side length of the dining hall on the map, we need to use the given scale of the map.
- The scale indicates that 1 cm on the map corresponds to 2 meters in reality.
- Since the actual length of the dining hall is given as 16 meters, we can convert this length to the map length using the scale.
Using the scale: \[ \text{Map length} = \frac{\text{Actual length}}{\text{Scale factor}} = \frac{16 \text{ m}}{2 \text{ m/cm}} = 8 \text{ cm} \]
So, the length of the dining hall on the map is 8 cm.
If one side is already labeled as 25 cm, the missing side length should also be 8 cm in the context of the dining hall's dimensions. Thus, you may want to double-check if you're interpreting the dimensions correctly; usually, both sides can't be larger than the actual building's dimensions.
In simple terms, the highlighted side length of the dining hall on the map would be 8 cm.
