From a maths point of view, is "10 metres squared" the same as "10 square metres" when talking about the area of a rectangle?

And are they both written 12 m²

where did the extra 2 square metres come from?

Seems an incorrect formulation which could mean either 10 square metres or 100 square metres.

Shout at the teacher.

10 metres squared is nonsense to me but if it means anything it's 10m² (see below)

If a rectangle is 10 metres square I'd assume it's 10m on each side i.e. a square with an area of 100 square metres.

If it's 10 square metres then it has an area of 10 square metres which could be written 10m²

E&OE. I do sums, but not maths any more.

If the answer to the original area question is 10m² then that could come from a rectangle of maybe 1m x 10m or 2m x 5m (or some other combination).

Well, as a mathematician who was in Set D (bottom set) in 1964 but who managed to get a Grade 3 at O Level (bloomin' miracle pass) I would say that 10 metres is 10 metres and if you square it you have 100 metres (in a straight line that Frank Budd could run in 9.2 seconds)
If on the other hand you have ten square metres and you square it ...........
I think you have 100 square metres but it could be 10 square metres x 10 square metres (100 square metres) and square it, could be 10,000 square metres ........
That's why I was in bottom set and only Jack Wilmut, maths teacher and father of the father of Dolly the cloned sheep got me that grade 3.
Think another glass is called for - got a funny feeling in my brain.
But if you want any further help on Maths questions you know where to go.......

If its 3m x 4m then I would assume that the area is 12 square metres.

That seems to be written as 12 m², although I would write it as 12sqm.

That may just be the naming/writing convention and that's the end of it. Fair enough.

However, if someone said 12 metres squared to me (which is how I would read 12 m²), then that would mean a 12m x 12m shape in my mind.

I hate the homework of a 7yr old, its so humbling.

The usual expression for a square measuring 12 metres by 12 metres is 12 metres square, not squared.

A square area of 10 square metres has sides of 3.16m (to two figures).

10 metres squared reflects badly on the maths teacher as although the answer is 100m, I'm not at all sure they meant to ask that question. They think they asked something else and will say 100m is a wrong answer.

I'm unclear, I got the impression from the original question that we are talking about the answer being 10m², therefore the teachers question might be something like "What two lengths would be needed to make a rectangle with an area of 10m²?".

I would have said that m² = metres squared, the same as m³ = metres cubed.

we have absolutely no idea what the original question was, its context or how it was worded.

all we have are the ramblings of a drunken ex pat.

"10 metres squared" is 10m x 10m = 100m2.

"10 square metres" is 10 m2

How would you say "10 m2" if you were reading it out?

10 square metres. Why don't you know that FMR? Is basic maths a lacuna in yr learning?

No, AC, its not. At least, I don't think it is.

When I was doing it we wrote cuft & sqft. I don't recall ever writing yard² or foot².

I'd be surprised if it was really. Just teasing.

"10 metres squared" is an expression of the lack of education of the writer.

"10 metres square" is a square that is 10 metres x 10 metres.

"10 square metres" is the area covered by ten carpet tiles that are 1m x 1m, and is the way to pronounce "10 m²".

Isn't that the same thing as

>> a square that is 10 metres x 10 metres.

?

Nooo, you'll need 100 carpet tiles of 1m x 1m to fill a square that is 10m x 10m.

Doesn't your wife complain that only one tenth of your drawing room is carpeted? (Meanwhile you claim that the new carpet cost only one tenth of what you feared...)

Ah right, gotcha.

Our drawing room has parquet flooring, thankfully.

Thanks Mapmaker, that works for me so that's how two Chilean Maths Teachers are going to be told.
