a) dimension of the area of the frame or the area between the photo with the frame and the photo without the frame:
length= length of photo with frame- length of photo without frame= 8-6= 2 cm
width: width of photo with frame- photo without frame= 6-4.5=1.5 cm
area of the frame= length × breadth
= 2×1.5= 3 cm^2
cost of polishing the frame = rate* area of frame
= 3×5 = rs 15 per sq cm.
