Answer:

1) 8m
From green bar, we can deduce that
the height of vertical bar = 2/3 of uninterrupted shadow length of the bar.
Therefore shadow of 6m of red bar indicates the height of 4m.
The remaining red bar casts a direct 1:1 vertical projection on the wall.
Therefore total length = 4m + 4m = 8m.


2) Answer is 8m long. This is because 3m of the horizontal shadow corresponds to 2m of height and the vertical shadow corresponds to 4m in height.

4m + 4m = 8m
