Question

the cost of fencing a square field at rupees 125 per metre is rupees 8000 find the length of each side of the field

Answer 1

thus the answer would be 16m

Answer 2

cost of fencing per metre = 125

total cost = 8000

then perimeter = total cost / cost per metre = 8000/125 = 64m

we know that perimeter of a square = 4s

64m = 4s

64m/4 = s

16m = s = length of each side
