We have some skylights and they measure 1.2m by 0.8m
Suppose both dimensions increase by 20%. What's the percent increase in
the amount of light admitted?
You have a newspaper the dimensions are
35cm by 38cm
they reduce the pages by 10%. There are 48 Pages in the newspaper,
daily circulation of 135,000.
Compare the area of the reduced page to that of the original,
expressed as a percent.
Any ideas on the proper way to do these? A formula and a explanation of why would be great!

ok.. so.. here's an example...
say we have some skylights... and they measure... 1.2m by 0.8m
suppose both dimensions increase by 20%. What's the percent increase in
the amount of light admitted? and no.. it's not 40%.
Solution. The original is 1.2m by 0.8m, so the area is . If both dimensions increase ...
This shows how to determine percent increase and decrease in area
