The length of longer pole that can be placed on the floor of a room is 10 m and the length of the longest pole that can be placed in the room is 10√2m. The height of the room is ?
-
- 6 m
- 7.5 m
- 8 m
- 10 m
Correct Option: D
∵ l2 + b2 = (10)2 = 100
And l2 + b2 + h2 = (10√300)2 = 200
⇒ h2 = (200 - 100) = 100
∴ h = 10 m
