    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!

    Thanks
