Question

A person of 1.8m tall stood near a pole of 30m height he casts 2.7m shadow find the length of the shadow of the pole at the same time

Answer 1

Answer:

45 meter

Step-by-step explanation:

Let, the length of the shadow be $x$

A.T.Q ,

$1.8 : 2.7 = 30 : x \\\frac{1.8}{2.7}  = \frac{30}{x}\\ \frac{2}{3} = \frac{30}{x}\\2x = 90\\x = \frac{90}{2}\\x = 45$

Hence, the length of the shadow is 45m
