Question

The cost of making a boundary line with barbed wine around a square field is rupees 1400 @ rupees 40 per metre find the length of the side of the field

Answer 1

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
