Question

Cost of fencing around a square field is ₹ 1200. If the cost of fencing per meter is ₹ 30, then area of the square field is ___

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.
