Question

A building 15 m high, casts a shadow 1.8 m long. What would the height of a pole be, if at the same time, its shadow is 60 cm?

Answer 1

$1.8$ m long shadow is casted by a building of height $15$ m

$180$ cm long shadow is casted by a building of height $1500$ cm

$60$ cm long shadow is casted by a pole of height $\frac{1500\times 60}{180}$ cm

$=500$ cm

$=5$ m
