Answer 2

Given:

Length of the rectangular field = 280m

Breadth of the rectangular field = 170m

Cost of fencing the field = ₹ 60 per metre

To find:

Cost of fencing the entire rectangular field.

Solution:

As we have to fence the field, therefore we will find the perimeter of the field first.

We know that,

Perimeter of rectangle = 2(l+b)

So,

Perimeter = 2 (280+170)

Perimeter = 2×450

Perimeter = 900m

Cost of fencing 1m of rectangular field = ₹60

Cost of fencing 900m of rectangular field = ₹(900×60)

=  ₹54,000

Final answer:

Cost of fencing the entire field at ₹60 per metre is ₹54,000.
