area = 0.5*base*height
area = 0.5*(x+2)*(x+9)
area = 0.5*(x^2+9x+2x+18) ... use the FOIL rule
area = 0.5*(x^2+11x+18)
area = 0.5x^2+5.5x+9

Side notes:
0.5 = 1/2
5.5 = 11/2

For your info:

        In a right triangle, the sides that are not the hypotenuse, are called the legs in English.

So, the normal smooth wording for your problem would sound this way:

In a right triangle, the legs are (x+2) and (x+9) units long. Write a simplified expression which represents the area of the triangle.
