Need help on this question, please.

The sides of a rectangle have lengths x+1 and widths x-5, Which equation below describes the perimeter, P, of the rectangle in terms of x?

[A] P= x2+6x-5

[B] P= 2x-4

[C] P= x-4

[D] P=4x-8

I'm thinking it's letter A because when multiplying two polynomials, you combine the terms.
