Two poles of height 6 m and 11 m stand vertically upright on a plane ground. If the distance between their foot is 12 m, then the distance between their tops is
Question and options
Two poles of height 6 m and 11 m stand vertically upright on a plane ground. If the distance between their foot is 12 m, then the distance between their tops is
- 12 m
- 14 m
- 13 m
- 11 m
Answer and explanation
Correct answer: C - 13 m
Height difference = 5 m and horizontal gap = 12 m, so the distance between the tops = sqrt(25+144) = 13 m.
