How high is a chimney whose shadow is 28 m. long when a five-foot gate cast a twelve-foot shadow?
:
Change 28 m to ft: 3.28*28 = 91.84 ft
The relation ship between the shadows is the same as the heights
:
let h = the height of the chimney
h%2F5 = 91.84%2F12
Cross multiply
12h = 5 * 91.84
12h = 459.2
h = 459.2/12
h = 38.27 ft
