7m 1.75 divided by 2.25 = 0.77777777... 0.77777777.. times by 9 = 7
b. 7 m ;
The height of the statue is 7 m, found by using proportional reasoning based on the lengths of the shadows cast by Jack and the statue. We set up a ratio comparing Jack's height and shadow length to that of the statue. This shows that if the shadow length is increased while the same light source is used, the height must also increase proportionally.
