Given information
Radio telescopes are designed to observe 21-cm waves
emitted by atomic hydrogen gas. A signal from a distant
radio-emitting galaxy is found to have a wavelength that is
0.10 cm longer than the normal 21-cm wavelength.
Step-by-step explanation
Step 1.
Expression for redshift parameter is
is redshift parameter
velocity
is speed
Redshift in terms of redshift parameter, this is calculated with an equation, where 
is the observed wavelength of spectral line and 
is the wavelength that line would have, if its source was not in motion.
By using Hubble's law expression is given by
Substitute the value of
