Answer 1

Step-by-step explanation:

Width = 50 m

cost of fencing = Rs. 18 per metre

Total cost = Rs. 4680

cost of leveling = 7.6 per m2

Area = 460 m2

1) Length

perimeter = 2 x ( length + width)

Total cost = costcost of fencing x perimeter

4680 = 18x ( 2 x ( L + 50))

L = (4680/( 18 x 2)) - 50

L = 130 - 50

L = 80 m

Therefore, Length = 80 m

2. Cost of leveling

cost = area x cost of leveling per sq m

cost = 460 x 7.6

= Rs. 3,496.00
