Correct option is B
Cost per Linear Metre Method:
This method involves calculating the cost of construction based on the linear measurement of the perimeter works, such as fencing, boundary walls, or other linear structures.
It is particularly suited for works where the cost depends on the length of the structure.
Purpose:
Used for quick and approximate estimates for perimeter-related works.
It provides an accurate basis when the linear extent of the structure (e.g., walls, railings) is the determining factor for cost calculation.
