Ok so your measurements of the tree is 23m, that's its shadow. The statue is 43cm long, which is its height, and the shadow is 79 long. What you could do is proportions.
So here's how I set it up
23/x=79/43
Now all you need to do is cross multiply.
23 times 43 is 989, 79 times x is 79x
79x=989
divide 989 by 79 and you get 12.5
Round that off and it's 13
The height of the tree is 13.
