Chapter: Similarity· Mathematics Part 2 (Geometry)
Answer: 6 m
The sun’s rays make the same angle with the ground for both objects and both stand vertically, so the two triangles (object, shadow, ray) are similar by the AA test. Hence \(\dfrac{\text{height}}{\text{shadow}}\) is the same: \(\dfrac{6}{4} = \dfrac{9}{s}\) \(\therefore s = \dfrac{9 \times 4}{6} = 6\) m.
