The area of the metal frame can be calculated using the following formula: Area of Metal Frame = (side length of frame)2 - (Area of Mirror) Plugging in the given values, we have: Area of Metal Frame = (15x)2 - (π × (5x)2) Simplifying this expression, we have: Area of Metal Frame = 225x2 - 25πx2 Therefore, the area of the metal frame can be written in factored form as: Area of Metal Frame = 25x2 (9 -π)
