Answer:
Rs.6647
Step-by-step explanation:
The boundary wall will be rectangular with two long sides and two short sides.
The total length of the boundary wall = 2 * (long sides) + 2 * (short sides)
long side (length) = 100m
short side (width) = 45.75m (75cm = 0.75m)
Total length of boundary wall = 2*100 + 2*45.75
= 200 + 91.5
= 291.5
Total length of the boundary wall = 291.5 m
Now, it is given that a stretch of 2.5m is left out for the entrance.
=> Effective length of the boundary wall = 291.5 - 2.5
= 289
The effective length of the boundary wall = 289 m
The rate of building the wall is Rs.23 per metre
=> Total cost of boundary wall = 289 * 23
= 6647
The total cost of building the boundary wall is Rs.6647
Here is your answer
Rs.6647
