#### Answer

$2b^{2}+22b$

#### Work Step by Step

We start with the given expression: $(b+11)(2b)$
We apply the distributive property to multiply the monomial by the binomial: $(2b)(b)+11(2b)$
We multiply the coefficients and add the exponents on each term to arrive at our answer: $$2b^{1+1}+22b$$$$2b^{2}+22b$$
