Answer:
18000rupees
Step-by-step explanation:
The dimensions of wall are:
length:25m
breadth=16m
he wants to build around his piece of land
For that he must know the perimeter of the land
perimeter of a rectangular field is given by:length×breadth
∴perimeter of rectangular field=25m×16m
∴perimeter of rectangular field=400m
now we know the price of building wall is 45rupees per meter
∴400×45=total cost to build wall
The total cost to build wall is 18000rupees
