Answer:
x^2 + 11x + 18.
Step-by-step explanation:
The length = x + 9 and the width = x + 2.
So the area
= length * width
= (x + 9)(x + 2)
= x(x + 2) + 9(x + 2)
= x^2 + 2x + 9x + 18
= x^2 + 11x + 18.

Since the two angles have a sum of 90 degrees, we can add the two expressions together and set it equal to 90.
