Answer:
Cost of fencing = Rs. 4000
cost of harvesting = Rs. 7500
Explanation:
Given :
side of square = 50 m
fencing rate per m = Rs .20
harvesting rate per sq.m = Rs .3
Perimeter of a square = 4 × side
= 4 × 50 = 200 m
Rate of fencing for 200 m = 200 × 20
= Rs.4000
Area of a square = side × side
= 50 × 50 = 2500sq .m
Rate of harvesting for 2500 sq.m = 2500 × 3
= Rs . 7500
