Perimeter means to add up all of the sides. Since it's a rectangle, you have 2 sides that have length b + 7, and 2 sides with length b. So, the polynomial is %28b%2B7%29%2B%28b%2B7%29%2B%28b%29%2B%28b%29. Simplified, that's 4 b's plus 2 7's: 4b%2B14.
Area is length times width, or base times height...basically, one side times the other. So, for you: %28b%29%28b%2B7%29. Distribute your b and you have b%5E2%2B7b.
