Answer:
Length of the side of the field = 8.75m
Step-by-step explanation:
Total cost = rupees 1400
cost for 1m = rupees 40
since the barbed wire is to be made into a boundary line around the square field i.e. around the perimeter of the field;
perimeter x cost for 1m = total cost
=> perimeter = 1400/40
=> perimeter of the square field = 35m
perimeter of a square = 4 x side
=> side = 35/4
=> length of the side of the square field = 8.75m
