The area of the patio is x^2 square feet because it is a square with side length x.
The area of the walkway is (x+5)(x+5) - x^2 square feet because it is the difference between the outer square and the inner square. Simplifying this expression, we get 25 + 10x square feet.
Therefore, the total area of the patio and the walkway is x^2 + (25 + 10x) square feet.
Combining like terms, the total area is x^2 + 10x + 25 square feet.
Therefore, the answer is D. (x^2 + 10x + 25) sq.ft.
