Explain your thinking:

Answer 1

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 square will be 7*5= 35 sq.inch.

Area of hollow surface 5*3= 15 sq.inch.

Area of frame = square area- hollow area= 35-15

Area of wooden portion of frame = 20 sq.inch.
