Answer 1

Given:

A flag pole 15m high casts a shadow of 3m at 10 a.m

To find:

The height of the building

Solution:

The given condition in the question is that

A flag pole 15m high casts a shadow of 3m at 10 a.m,

which means the height of the shadow of the flag pole is five times of the height of the flag pole.

At the same time, the shadow of the building is 18.6 m

So the height of the building will be one-fifth of the height of the shadow of the flag pole.

H = 18.6/5

H = 3.72 m

The height of the building is 3.72 m
