Answer:
The Number of trees = 2020 trees
The total cost of planting trees = Rs. 151500
Step-by-step explanation:
Given,
- The side of square field = 45m
- The area of well 5 sq. m.
- The area of 1 coconut tree is 1 sq. m.
- The cost of planting 1 tree is Rs. 75.
To Find,
- The Number of Coconut trees.
- The cost of planting the Coconut trees.
Solution,
The area of Square field = Side × Side
→ The area of Square field = 45m × 45m
The area of Square field = 2025 sq. m
The area of well = 5 sq. m
The area that all trees occupies = 2025 sq. m - 5 sq. m
The Total area that all trees occupies = 2020 sq. m
The Number of trees = The total area that all trees occupies / The Area covered by 1 tree
→ The Number of trees = 2020 sq. m / 1 sq. m
The Number of trees = 2020 trees
The cost of planting trees = Rs. 75 per tree
The total cost of planting trees = 2020 trees × Rs. 75 / trees
The total cost of planting trees = Rs. 151500
Required Answer,
- The Number of trees = 2020 trees
- The total cost of planting trees = Rs. 151500
