The length of the shadow of a tree of height 5.4 m is 9.6 m. At the same time, the length of the shadow of a building 43.2 m high is:
Answer & explanation
Correct answer: option 2
The given ratio of height and length:
⇒ Tree : Shadow = 5.4 : 9.6 = 9 : 16
*At the same time the above ratio remains same*
Therefore, ratio of height and length:
⇒ Building : Shadow = 9 : 16
Here,
⇒ 9R = 43.2
⇒ Length of shadow = 16R = \(\frac{43.2}{9}\) × 16 = 76.8
