Question

A farmer has a square field that is 60 m wide.
(a) Find the cost of fencing the field if it costs * 12 per metre.

​

Answer 1

Step-by-step explanation:

Given that:

What is the cost of fencing a square garden whose each side is 12 m long and if cost of fencing is Rs. 2.5/m?

According to question,

Each side of square = 12 m

Cost of fencing per meter = Rs. 2.5

For fencing the square garden we need to ascertain perimeter of the square.

Perimeter of square = 4a

Where a = side of the square

Each side of square = 12 m

Perimeter of square = 4a = 4 × 12 m = 48 m

Cost of fencing per meter = Rs. 2.5

Total cost of fencing=48 m×Rs. 2.5=Rs. 120

Hence, the cost of fencing a square garden whose each side is 12 m long = Rs. 120
