The area = π r² = π * 18² = 324 π in²
The first choice is the correct
The length of given frame is 7 inches
The width of given frame is 5 inches
Assume the thickness of frame is 1 inches (as it is not clear in picture)

Area of frame = square area- hollow area= 35-15
Area of wooden portion of frame = 20 sq.inch.
