Answer 2

Step-by-step explanation:

Given:

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

According to question

Each side of square = 12m

cost of fencing per meter = Rs. 2.5

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

Perimeter of the square = 4a

where a= side of the square

Each side of square = 12m

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

cost of fencing per meter = Rs. 2.5

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

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