You can put this solution on YOUR website! A circular mirror is surrounded by a square metal frame. The radius of the mirror is 7x. The side length of the metal frame is 21x. What is the area of the metal frame?
----------
Area of the rectangle = (21x)^2 = 441x^2
Area of the circle = pi*r^3 = 49pi*x^2
-------
The area of the frame is the difference.
