Question

A pole, 28 metres high casts a shadow of 20 metres. Find the height of a building that cast a shadow
of 30 metres under similar conditions.​

Answer 1

Answer:

As shadow is directly propotional to height, we can say that,

Height/Shadow =k, where k is a constant.

So, in case of electric pole,

1410=k→(1)

In case of tree,

HT15=k→(2), where HT is height of tree

So, from (1) and (2),

1410=HT15

HT=14∗1510=21m

So, height of tree is 21 meters.

Answer 2

Answer:

21meters is the right answer
