Answer:
Length (Tallness) of tree = 27 m
Step-by-step explanation:
Pole length = 9 m
Pole shadow = 12 m
Pole Shadow : Length Ratio = 12 : 9 = 4 : 3
Tree shadow = 36 m
As per 'Shadow : Length' ratio = 4 : 3
36 : L = 4 : 3
Reciprocal, L : 36 = 3 : 4
L / 36 = 3 / 4
L = ( 36 x 3 ) / 4 = 108 / 4
Tree length = 27 m
