Answer 1

Answer:

its 100 metre tree of 25 metre shadow

Answer 2

Answer:

is this what you were looking for?

Step-by-step explanation:

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
