## Q- There is a squared park in our locality. The area of a rectangular Park is 78 sqm less than the twice of the area of that square shaped Park whose length is 5 m. more than the length of the side of that park and the breadth is 3 m. less than the length of the side of that park. Let us right by calculating, the length of the side of the square shaped Park.
