Answer:
34.72 feets
Step-by-step explanation:
Using the relation :
Length of tree / shadow of tree = height of melody / shadow of melody
From the details given in the question :
Let height of tree = h
h / 62 = 5.6 / 10
Cross multiply
h * 10 = 62 * 5.6
h = 347.2 / 10
h = 34.72 feets
Hence, the height of tree is 34.72 feets
Total = Principal × ( 1 + Rate ) ^ years
(Solved by taking logarithms)
Years = log (total / principal) / (log (1 + rate))
Years = log (684 / 600) / (log 1.07)
Years = log (1.14) / (log (1.07)
Years = 0.0569048513364726 / 0.0293837776852097
Years = 1.9366077414
