A person has purchased two adjacent plots, one is in rectangular shape and other is in square shape and combined them to make a single new plot. The breadth of the rectangular plot is equal to the side of the square plot and the cost of fencing the new plot is Rs. 470 (Rs. 5/m). Find the side of square if the length of the rectangular plot is 20 m.
