In fact 
convert -sample 80x40 abbeyparkarch.gif s_abbeyparkarch.gif
automatically respects ratio, so only the y dimension is guaranteed

convert -resize 80  abbeyparkarch.gif s_abbeyparkarch.gif
respects ratio width 80

convert -resize x40  abbeyparkarch.gif s_abbeyparkarch.gif
respects ratio height 40
