A circular mirror is surrounded by a square metal frame.
The radius of the mirror is 2x. The side length of the metal frame is 10x.
What is the area of the metal frame
Metal frame are = square area - mirror area
A = %2810x%29%5E2+-+%28pi%2A%282x%29%5E2%29
A = 100x^2 - 12.566x^2
A = 87.434x^2 sq/units
