Question

An electric pole 18 m high casts a shadow of
10 m. What would be the length of the shadow
of a pole 14.4 m high 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.
