Answer
Since we know the diameter of the mirror frame to be 3ft and the circular mirror inside to be 1.5ft and we are asked to find the area of the circular mirror frame
Solution
Radius of the circular frame=d/2=3/2=1.5ft
Radius of the circular mirror inside=1.5/2=0.75ft
Area of the circular mirror frame=piR^2-pir^2
=3.14x1.5x1.5-3.14x0.75x0.75
=7.065-1.77
=5.295ft^2

Therefore 5.295ft^2 is the area of the circular mirror frame.
