A rectangular park is 55 m by 45 m. A path 2.5 m wide is built all aro...
Given:
- Length of the rectangular park = 55 m
- Width of the rectangular park = 45 m
- Width of the path = 2.5 m
- Cost of grassing per square meter = Rs. 10

To find:
The cost of grassing the remaining part of the park

Explanation:
To find the cost of grassing the remaining part of the park, we need to calculate the area of the remaining part.

Step 1: Calculate the area of the park:
The area of the park can be calculated by multiplying the length and width of the rectangular park.

Area of the park = Length × Width
= 55 m × 45 m
= 2475 m²

Step 2: Calculate the area of the inner rectangle:
The inner rectangle is formed by subtracting twice the width of the path from the length and width of the park.

Length of the inner rectangle = Length of the park - 2 × Width of the path
= 55 m - 2 × 2.5 m
= 55 m - 5 m
= 50 m

Width of the inner rectangle = Width of the park - 2 × Width of the path
= 45 m - 2 × 2.5 m
= 45 m - 5 m
= 40 m

Area of the inner rectangle = Length of the inner rectangle × Width of the inner rectangle
= 50 m × 40 m
= 2000 m²

Step 3: Calculate the area of the remaining part:
The area of the remaining part can be obtained by subtracting the area of the inner rectangle from the area of the park.

Area of the remaining part = Area of the park - Area of the inner rectangle
= 2475 m² - 2000 m²
= 475 m²

Step 4: Calculate the cost of grassing the remaining part:
The cost of grassing the remaining part can be calculated by multiplying the area of the remaining part by the cost per square meter.

Cost of grassing the remaining part = Area of the remaining part × Cost per square meter
= 475 m² × Rs. 10/m²
= Rs. 4750

Answer:
Therefore, the cost of grassing the remaining part of the park is Rs. 4750, which is not among the given options. So, the given options might have a typographical error or the calculation might have been done incorrectly.
