This is the same code I commented on, I don't see that you took up any of my suggestions here.

Land Area: <%= land_area %> <%- if land_area_unit == 'M2' %>m&sup2;<%-
else %><%= land_area_unit %><%- end %>

Which could arguably be written a lot more neatly:

Land Area: <%= "#{land_area} #{(land_area_unit == 'M2')? 'm&sup2;' : land_area_unit}".html_safe %>

Still quite a mess to have in your view, though.
