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
