The surface of interest can be parameterized by
with
and
.
The area of the surface
is given by the surface integral
We have
so the area is given by the double integral
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.
