A new public park in Mumbai covers an area of 2500 square meters. If the park planners want to plant 30 trees per 100 square meters to ensure adequate shade, how many trees should they plant in total?
Answer
750 trees
The correct answer is 750 trees — Therefore, 750 trees are required.
Step-by-step solution
- Divide the park area by 100 to find the number of 100 m² blocks: 2500 m² ÷ 100 m² = 25.
- Multiply the number of blocks by the tree density: 25 × 30 = 750.
- Therefore, 750 trees are required.
Common mistake: Multiplying by 30 directly on area instead of per block.
Concept tested: Tree density calculation
