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.
