Maths Problem - Which monitor is the biggest?

Discussion in 'Mathematics' started by shirtandtie, May 17, 2011.

  1. I went to the local computer store to buy a replacement monitor for my home PC.
    My existing monitor is 19", that is to say the diagonal dimension is 19", and I am happy with this size.
    There were two types of 19" monitors in the store; 'widescreen' ones with a 16:9 aspect ratio, and 'normal' ones with a 4:3 ratio. The second type were not as wide, but they looked bigger.
    But which one was bigger? And how much bigger was it?

    Forget about it being a maths question ( simple question on areas ) and go for the one which is more useful for you to work with.
  3. Depends on what you mean by "bigger" ... area? width? height?
    I've done a couple of activities in the past where there is no right answer, and then given each group a point to "argue" and they must then see how the maths can back up their argument.
    You can then set up a mini (not mass!) debate.

    That aside ... do they still sell 4:3 monitors?!?!
  4. Is there some significance in 16:9 being the square of 4:3?
    Just wondering.
  5. BTW, I forgot to add that it is now possible to get monitors that can be rotated by 90 degrees in the vertical plane. Apparently all you e-markers will benefit from such devices.
    I expect you all knew that.
  6. Based on area you're correct, 4:3 is bigger. 4:3 are 15.2 x 11.4 giving approx 173 sq in and 16:9 are 16.56 x 9.31 giving approx 154 sq in. About 19 sq in more.
  7. Gone for the 4:3 (actually had to order it - difficult to find in a shop).
    It's so much better, not because it's 12% bigger, (thanks to the above posters for that), at no significant extra cost, but because it's so much better for 'office' work.
