Answer:

Cost of fencing per metre = Rs 30 Total cost of fencing = Rs 12000 So, the length of fencing (perimeter) = Total cost/ Cost per metre = 1200/30 = 400 m Now, length of fencing = Perimeter of the square field = 4 × side of the field Therefore, 4 × side of the field = 400 m or, side of the field = 400/4 m = 100 m So, area of the field = 100 m × 100 m = 10000 sq m.
