Answer:
b. 7 m
Step-by-step explanation:
There is a direct proportion relationship between the length of the object/person and the shadow cast by it.
Let the length of the object/person be L an that of the shadow be B
L ∝ B
L = KB
where K is the constant of proportionality.
Where L = 1.75 m, B = 2.25 m
1.75 = 2.25B
B = 175/225 = 7/9
Therefore, L = (7/9)B
If at the same time, a statue casts a shadow 9 m long, then B = 9 m
L = (7/9) × 9
L = 7 m
The height of the statue is 7 m.
