The breadth of a rectangle is 40% less than its length. The perimeter of the rectangle is 52 m more than the circumference of a circle, which is inscribed in a square. If the difference between the area of the square and the area of the circle is (x + 20) m2 and the sum of the perimeters of the rectangle and the square is 152 m, find the value of x. (Take π = 227)
