The cost of fencing a rectangular field at the rate of Rs. 5 per meter is Rs.350. If the length of the field is 15 meters more than its breadth, then find the length of the rectangular field.
Let the length of the rectangular field be ‘x’ meter. Breadth of the field = (x – 15) meter. Therefore, perimeter of the field = 2 [x + (x + 15)] = (4x + 30) meter According to the question, => 4x – 30 = 350/5 => 4x = 70 + 30 => x = 25 meters
