Question

The length of a man's shadow is directly proportional with his height.

At the same time of day, a man who is 1.8 meters tall casts a 25.2
meter shadow and his son casts a 21 meter shadow. What is the
height of the man's son, in meters? If necessary, round to the nearest
tenth.

Answer 1

The man's son height is 1.5m

Explanation:

`(x)/(21) =(1.8)/(25.2)`

`(21x1.8)/(25.2)`

21x1.8= 37.8

37.8 ÷ 25.2= 1.5

Hope this helps
