The L-shaped desk has two parts: a rectangular part and a triangular part.
Surface of rectangular part = length x width = 35in x 55in = 1925 sq in
Surface of triangular part = 1/2 x base x height = 1/2 x 22in x (40in - 1in - 1in) = 420 sq in
Total surface area of the desktop = surface of rectangular part + surface of triangular part
= 1925 sq in + 420 sq in
= 2345 sq in
Therefore, the surface of the desktop is 2345 square inches.
