Multiple choice

Two poles of heights 6 m. and 11 m. stand on a flat ground. If the distance between their feet is 12m, what will be the distance between their tops? 6 मीटर और 11 मीटर ऊँचे दो खम्बे एक समतल पर स्थित है, इनके तल के बीच की दूरी 12 मी. है। तद्नुसार उनके शिखर के बीच की दूरी क्या है?

  1. 10 m./मी.

  2. 11 m./मी.

  3. 12 m./मी.

  4. 13 m./मी.

D Correct answer
Explanation

The height difference between poles = 11 - 6 = 5 m. Horizontal distance between feet = 12 m. These form a right triangle where the distance between tops is the hypotenuse. Using Pythagoras: Distance = √(5² + 12²) = √(25 + 144) = √169 = 13 m.
