maths question

[Chipman]

This one?

I don't understand one bit. Can someone please explain it to me.

Some of us suspect that Spirit was trying to be tricky... apart from the obvious 3x2 or 6x1 pattern, what if he meant the perimeter of the shape once all the rectangles were put together in a square...the edges of the rectangles "disappear" on the inside of the square once they are put together. Thus 4 sides - 330 cm etc as claw hama said

Don't forget this boys. There are 3 simple steps in maths.

1. Read the question
2. Think
3. Answer the question

C'mon boys don't jump steps. Let's start from step 1 again.

Let's read it together

A square is formed by 6 rectangles- given the total perimeter of the 6 rectangles is 330cm.

determain the area of the square

[Wongo]

No it is not tricky. It is a very simple question.

A square is formed by 6 identical rectangles- given the total perimeter of the 6 rectangles is 330cm.

Why am I so sure they are identical?? Because if they are not then there will infinite number of solutions.

Spirit, you are not kidding are you?

[SPIRIT]

why

[Wongo]

Why didn't you show the diagram from the begining?

1. 1089
2. x*x / 100

[Wongo]

why

Because with the picture your question has only 1 answer. Without the picture your question has countless answers.

how did you work it out?

[Chipman]

Hey Wongo,

I checked out Spirit's other posts and to me this is his style.... he reveals things bit by bit! But give him credit, he sure gets us all interested.

None-the-less I agree, the diagram should have been their right from the start!!!!

A picture is worth a thousand words

[Chipman]

Wongo, I really like the way you solved that!!!!

Excuse the pun but that really is thinking outside the box!

Well done, Wongo.
The thing with these problems is, you need to see the whole problem! If Spirit is going to drip feed us, there's no point.

[Wongo]

Sorry I made a mistake. The answer to the second part of the question is

(x/10)^2 or x*x / 100

[Wongo]

Well done, Wongo.

Well Alex I think without the picture the question becomes far more interesting. With it, it is too easy.
