shadow casted by 10.5 m pole = S'
" " " 5.6m. " = S
=>S'/S = 10.5 /5.6
=> S' = 1.875 * S = 1.875 * 3.2 =6m
Now, Shadow casted by third pole S'''=5
V. Height of pole = V'
V'/V = 3.2/ 5
=> V' = ( 3.2 /5 ) * 5.6
=> V' = 3.6m
" " " 5.6m. " = S
=>S'/S = 10.5 /5.6
=> S' = 1.875 * S = 1.875 * 3.2 =6m
Now, Shadow casted by third pole S'''=5
V. Height of pole = V'
V'/V = 3.2/ 5
=> V' = ( 3.2 /5 ) * 5.6
=> V' = 3.6m
