To find the length of the shadow of the tree at midday, we can follow these steps:
1. In the morning, the shadow is 50.4 m long.
2. By midday, the shadow is a quarter of its morning length.
3. To find the length of the shadow at midday, we need to calculate a quarter of 50.4 m.
Calculation:
- 50.4 m / 4 = 12.6 m
Therefore, the length of the shadow of the tree at midday is 12.6 meters.
