1. At the same time that of a 60 feet tall building casts a sadow that 21.5 long, a nearby tree casts a sadow that is 18 feet long. Which measure is closest to the height of the tree?/৬০ ফুট উচু একটি দালানের ২১.৫ ফুট দীর্ঘ ছায়া হয়। একই সময়ে একটি গাছের ছায়ার দৈর্ঘ্য ১৮ ফুট হলে, গাছের উচ্চতা কত?
- A. 56.5 ft
- B. 56.5 ft
- C. 56.5 ft
- D. 56.5 ft
Answer: Option B
Explanation:
Two similar right angle triangles can be drawn from the given information.
Now, height of the tree/height of the building = shadow of the tree/ shadow of the building
Therefore, height of the tree = (18/21.5) x 60 = 50.2
