Question

12. The length of the shadow of a 100 m high
building is 72 m at a particular time. Find the
length of a tower whose shadow is 18 m long at
the same time.​

Answer 1

Answer:

25 metres

Step-by-step explanation:

Let the tree's length be x.

The ratios of the shadow and the building's shadow and the tree and the tree's shadow are equal as time is same.

=> 100 : 72 = x : 18

$=>\frac{100}{72} = \frac{x}{18} \\ = > x = \frac{100}{72} \times 18 \\ = > x = \frac{100}{4} = 25 \: m$
