Using 55.8 pb{sup -1} of e{sup +}e{sup -} collisions recorded at the {psi}(3770) resonance with the CLEO-c detector at CESR, we determine absolute hadronic branching fractions of charged and neutral D mesons using a double tag technique. Among measurements for three D{sup 0} and six D{sup +} modes, we obtain reference branching fractions B(D{sup 0}{yields}K{sup -}{pi}{sup +})=(3.91{+-}0.08{+-}0.09)% and B(D{sup +}{yields}K{sup -}{pi}{sup +}{pi}{sup +})=(9.5{+-}0.2{+-}0.3)%, where the uncertainties are statistical and systematic, respectively. Final state radiation is included in these branching fractions by allowing for additional, unobserved, photons in the final state. Using a determination of the integrated luminosity, we also extract the cross sections {sigma}(e{sup +}e{sup -}{yields}D{sup 0}D{sup 0})=(3.60{+-}0.07{sub -0.05}{sup +0.07}) nb and {sigma}(e{sup +}e{sup -}{yields}D{sup +}D{sup -})=(2.79{+-}0.07{sub -0.04}{sup +0.10}) nb.
