The length of the shadow of a tree of height 2.6 m is 6.5 m. At the same time, the length of the shadow of a building 20.2 m high is:

50.5

The given ratio of height and length:

⇒ Tree : Shadow = 2.6 : 6.5 = 2 : 5

*At the same time the above ratio remains same*

Therefore, ratio of height and length:

⇒ Building : Shadow = 2 : 5

Here,

⇒ 2R = 20.2

⇒ Length of shadow = 5R = \(\frac{20.2}{2}\) × 5 = 50.5 m
