the length of the shadow of a tower 153 m high is 45m at a particular time. find the height of an electric pole whose shadow is 20m long at the same time
Answers
Answer:
The height of electric pole is 68m
Step-by-step Explanation :
Given : Height of Tower = 153m.
Length of shadow of Tower = 45m
Length of Shadow of Pole = 20m
To find : Height of Pole = ?
We know that,
More the Height of Tower, Longer will be the Shadow.
So, the Height and length of Shadow are in direct proportion.
As a result we can say that the height of electric pole will be. Less than height of Tower.
So,
153 m height ------------ 45m shadow
? Height ------------- 20 m shadow
( Just simply doing cross multiplication )
153 × 20 / 45 = height of Electric pole
68m = height of electric pole
Hence the height of electric pole is 68m
( We can verify our answer as the height of electric pole is less as compared to height of Tower and same goes with length of Shadow too )
