Question

find the height of a flagpole which casts a shadow 20m long at a time and place where the shadow of a stick 1mlong is 55cm​

Answer 1

Answer:

The height of the flag pole = 36.36 m

Step-by-step explanation:

The height of stick = 1m

The height of its shadow = 55cm = 0.55m

The height of the flag pole be x m

The height of its shadow =20 m

It is in direct proportion. So,

height of the object/ height of the shadow = constant

$\frac{1}{0.55} = \frac{x}{20} \\ by \: cross \: multiplication \: we \: get \\ 0.55x = 20 \\ x = \frac{20}{0.55} =36.36m$
