I Have A Mathematical Question .... Who Can Help?

Feel free to talk about anything that you want.

Postby bill cobbett » Fri Jan 26, 2007 4:10 pm

Speaking of four dimensions leads me to something that worries me about measuring land areas in somewhere like the more hilly areas of Cyprus. I would say that the third dimension ( the up/down one) becomes important.

Is the land area the area within a hypothetically flat surface bounded by a perimeter of appropriate length? In the example of a hectare that would be a boundary, if it were square, of 100m x 100m but in cases where the ground enclosed by this perimeter were undulating, you could make a case that this square contained more than a hectare.

I wonder whether this might explain why our beloved property developers are sometimes a bit optimistic when it comes to land area.

An interesting point. I'll ask my grandson who is apprenticed to a surveyor.

devil,

To explain: it depends on the order of the words:

If someone has a plot of say 1,000 sq, yards - whatever the shape of the plot - that is the total area i.e. 1,000 sq. yards.

However , if the plot was described as being 1,000 yards square, that means it measures 1,000 by 1,000 i.e. 1,000,000 sq. yards.

My grandson's answer:
Well land is sold "by square meter" but it's always calculated from a plan so it would be 10'000 m2...
But it's a good question for sloping mountain lands, I guess it's the same...

Hope that's the answer you wanted.

You haven't got it. An acre - or a hectare - is an area, not a linear dimension. You simply cannot have a square acre, as that would take it to the fourth dimension. You cannot have a square square foot, either, can you? A (m²)² is geometrically impossible. :D

devil,


Yes, an acre is a measurement of area (as are sq. metres, kms etc.)

Why can you not have a square plot of land that encompasses an area equating to an acre ?. After all an acre can be any shape.

The original question related to a square area.

p.s. The 'old spice' quip was quick !

Okay, try this test.

Test for Dementia

Below are four (4) questions and a bonus question. You have to answer them instantly. You can't take your
time, answer all of them immediately. OK?


Let's find out just how clever you really are....



Ready? GO!!! (scroll down)












First Question:

You are participating in a race. You overtake the second person. What position are you in?







~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~




Answer: If you answered that you are first, then you are
absolutely wrong! If you overtake the second person and you take his place, you are second!

Try not to screw up next time.
Now answer the second question,
but don't take as much time as you took for the first question, OK?

Second Question:
If you overtake the last person, then you are...?
(scroll down)











~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~




Answer: If you answered that you are second to last, then you are wrong again. Tell me, how can you overtake the LAST Person?


You're not very good at this, are you?










Third Question:
Very tricky arithmetic! Note: This must be done in your head only.
Do NOT use paper and pencil or a
calculator. Try it.



Take 1000 and add 40 to it. Now add another 1000 . Now add 30.
Add another 1000. Now add 20. Now add another 1000
Now add 10. What is the total?


Scroll down for answer.....









~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Did you get 5000?

The correct answer is actually 4100.



If you don't believe it, check it with a calculator!
Today is definitely not your day, is it?
Maybe you'll get the last question right....
....Maybe.



Fourth Question:

Mary's father has five daughters: 1. Nana, 2. Nene, 3. Nini,
4. Nono. What is the name of the fifth daughter?







~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Did you Answer Nunu?
NO! Of course it isn't.
Her name is Mary. Read the question
again!



Okay, now the bonus round:

A mute person goes into a shop and wants to buy a toothbrush. By
imitating the action of brushing his teeth he successfully
expresses himself to the shopkeeper and! the purchase is
done.
Next, a blind man comes into the shop who wants to buy a pair of
sunglasses; how does HE indicate what he wants?









~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



He just has to open his mouth and ask...
It's really very simple.... Like you!











PASS THIS ON TO FRUSTRATE THE
SMART PEOPLE IN YOUR LIFE!

You could have a square plot of one acre, of course, but I reiterate, it is not a square acre.

I know of an Irishman who argued with his father, he accused him of wasting his life on drink, "I would love to have been able to start up a farm!" he said, "But you never gave me any help!"
Whereupon the father gave his son a good kick in the bollocks and said,
" There you are now son, there's a couple of achers for you to start off with!"
