A 2 m person casts a 1.5 m shadow. A nearby skyscraper casts a 15 m shadow. Find the height of the skyscraper.
Show answer & explanation
Correct answer: B
Explanation
Given:
Person's height = 2 m
Person's shadow = 1.5 m
Building's shadow = 15 m
Formula:
Height / Shadow = Equal
2 / 1.5 = h / 15
1.5h = 2 × 15
1.5h = 30
h = 30 / 1.5 = 20
