Answer:
The area of the metal frame will be 1232x².
Step-by-step explanation:
The radius is 7x of the circular mirror is.
So, the area of the mirror will be = π(7x)² = [tex]\frac{22}{7} \times 49x^{2} = 154x^{2}[/tex].
Now, the radius up to the outside of the frame of the mirror id 21x.
So, the area of the mirror with the frame will be = π(21x)² = [tex]\frac{22}{7} \times 441x^{2} = 1386x^{2}[/tex].
Therefore, the area of the metal frame will be = (1386x² - 154x²) = 1232x². (Answer)
