Answer:
555 m
Step-by-step explanation:
Because the model should have identical proportions to the real-life tower, the ratio between the height and shadow length of both diagrams should be the same.
Height (model) Height (real)
------------------------- = ------------------------
Shadow (model) Shadow (real)
Math:
0.9 meters x
-------------------- = ---------------------- <----- Ratio
0.2 meters 123.3 meters
4.5 = x / 123.3 meters <----- Divide 0.2 from 0.9
555 meters = x <----- Multiply both sides by 123.3
