☆ Solution ☆
Given :-
- An electric pole casts a shadow of length 10 m at a particular time when a tree 8 m high
- casts a shadow of length 6 m .
To Find :-
- The height of the pole.
Step-by-Step-Explaination :-
Let height of electric pole be "h" m.
Shadow = 10 m and height = h m = for electric pole
Shadow = 6 m and height = 8 m = for tree
Now,
For tree and electric pole
=> Height : Shadow
=> 8 m : 6 m
=> h = 10
By cross multiplication,
=> 8 × 10 = h × 6
=> 80 = 6h
=> 6h = 80
=> h = 80 / 6
=> h = 13.34 m
Hence,
- The height of electric pole is 13.34 m.
