Solution
The correct option is C ₹7040
Side of a square field = 55 m
Hence, the perimeter of square field
= 4 × side = 4 × 55 m = 220 m
We know that the length of fence required to enclose the field is the perimeter of the square field.
Therefore, the length of fence = 220 m
Given,
Cost of fencing per metre = ₹32
Hence, total cost of fencing the field
= Length of fence × cost of fencing
= 220 m × ₹32/m = ₹7040
Side of a square field = 55 m
Hence, the perimeter of square field
= 4 × side = 4 × 55 m = 220 m
We know that the length of fence required to enclose the field is the perimeter of the square field.
Therefore, the length of fence = 220 m
Given,
Cost of fencing per metre = ₹32
Hence, total cost of fencing the field
= Length of fence × cost of fencing
= 220 m × ₹32/m = ₹7040
