The parameter of a square is double the perimeter of a rectangle. The area of the rectangle is 480 sq cm. Find the area of the square.

Let the side of the square be a cm. Let the length and the breadth of the rectangle be l cm and b cm respectively. 
4a = 2(l + b) 
2a = l + b 
l . b = 480 
We cannot find ( l + b) only with the help of l . b. Therefore a cannot be found . 
Area of the square cannot be found.
