The area of the mirror room is 49pi sq ft (about 153.9 sq ft).

Explanation:

The radius of a circle is half the diameter, so the radius is 1/2 * 14 = 7.
The equation of the area of a circle is A=pi*r^2. Substituting 7 for r, we get the area of the mirror room to be 49pi feet squared. This is approximately 153.9 feet squared.
