Answer:
4 feets
Step-by-step explanation:
Given that :
Height of tree = 20 feets
Shadow of tree = 15 ft
Height of student = 5ft 4 in ; 4 in = 0.3333 foot = 5.3333 feet
Shadow of student = s
Height of tree / shadow of tree = height of student / shadow of student
20 / 15 = 5.33333 / s
Cross multiply :
20 * s = 15 * 5.33333
s = 79.99995 / 20
s = 3.9999975
Shadow of student =, 4 feets
