Answer»

☆ 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.
