The height of red bar - Math Riddle
Can you determine the height of red bar with the help of information provided in the picture below?
Explanation : 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.
