Just apply the golden rule.
"He who has the gold makes the rules"
2L + 2W = 90 and L = 25Quote:

now wisdom thats what we need at our schools work hard climb up off that bench and get of the field and be a playerQuote:

L is 25cm more than W. Therefore L > 25cm.
No wonder the country is going down the gurgler :rolleyes:
I bet they put that line break in there to sort out the ones who can read more than one line at a time from the ones who can't.
now l must know how long did it take to work out the first question
now you must say this a better debate than clean your room rebate for the morning:U
Ability to read and understand the question is just as important as getting the answer.
If you can show that you understand the question, show the calculation steps clearly but get the wrong answer you should still get some marks in an exam, at least that was the way I was taught 50 odd years ago.
If each person is allowed to put their own slant on a question the system fails.
Imagine the final result if engineers each interpreted calculations for a bridge in their own way.
There has to be a standard.
I still want to know how they read newspapers if they mentally insert a comma at every line break!
Thats why we try to keep everything we do looking the same as everything else we've done. We try toQuote:

And newspapers justify all their text to fit the line, they dont leave three quarters of the line empty before continuing the sentence on the next line.
Do you know how often they find mistakes in high school exams and uni exams? It is not uncommon. Student always end up getting full mark for the question.
Have I ever proven my 4 unit maths teacher wrong? Yes, a number of times. Have I ever been wrong? Yes, many many times.:D So it is all about if you have the conviction to stand up and question it.
If the argument here is about the interpretation of the question then this simple maths question has become a “trick question”. And we all know that trick questions are not for smart people. They are for smartarses.
We don't have the original exam paper in front of us to be able to say whether they did that or not. The point is, it is ludicrous to suggest that a carriage return implies a comma in the absence of a full stop. And you know it.Quote:

A rectangle has a perimeter of 90cm .the length of the rectangle is 25 cm
more than the width
OK someone please tell me. What the hell is "more than the width" for then?
And how come there is a space between 90cm and . but none before the t
How come it is "the length" not "The length"
:((
According to these knuckleheads, it means that the length of the rectangle is 25cm, which is more than the width.
Less than a minute but longer than it should have:rolleyes:Quote:

Maths is next period, I will write it up on the board exactly as it is here with the line break and see how long to get the correct (350) answer. Also will see how many come up with the wrong interpretation.
