    The cost of putting a fence around a square field at ₹ 35 per meter is ₹ 4480. The length of each side of the field is 32 m.
    Given that the cost of putting a fence around a square field at ₹ 35 per meter is ₹ 4480.
    Perimeter of field is,
    = cost of fencing square field cost of fencing per meter  
    = 4480 35  
    = 128 m
    Also, perimeter of square =4×side  . Equating both values,
    4x = 128
    x = 128 4   x = 32 m
    Length of each side is 32 m.
