The length of the shadow of a tree of height 3.9 m is 9.1 m. At the same time, the length of the shadow ( in meter ) of a building 46.2 m high
Answer & explanation
Correct answer: option 2
The given ratio of height and length:
⇒ Tree : Shadow = 3.9 : 9.1 = 3 : 7
*At the same time the above ratio remains same*
Therefore, ratio of height and length:
⇒ Building : Shadow = 3 : 7
Here,
⇒ 3R = 46.2
⇒ Length of shadow = 7R = \(\frac{46.2}{3}\) × 7 = 107.8 m
