Answer:
Area of rectangle = L x B
= (9x + 6) (2x - 2)
= 9x (2x - 2) + 6(2x - 2)
= 18x^2 - 18x + 12x - 6
= 18x^2 - 6x - 6

Step-by-step explanation:
the top surface of table is rectangle.
Length = (9x + 6), breadth = (2x -2)
Area of rectangle = L x B
= (9x + 6) (2x - 2)
= 9x (2x - 2) + 6(2x - 2)
= 18x^2 - 18x + 12x - 6
= 18x^2 - 6x - 6
therefore area of the surface is (18x^2 - 6x - 6) sq.inch
