Year 7 High School Maths

[Alz_D]

So I've been doing some homework with the partners 11 year old and came up against this:

Question is to work out the area, measurements are in m2 and this is the last of many.



I've drawn it exactly as it is in the book - makes a point of it not being to scale.

So how the hell do you work that out then?

Surely there is a measurement missing?

Moh nevermind im clearly not well this morning.

 

[touch]

Yep, I'd say there's something missing.

I looked at that picture for about 15 minutes last night and got nothing - I just want to make sure I've not forgotten some key maths that I learnt 25 plus years ago

 

[something daft already!!]

Nothing is missing. Only the answer

You can work out the gap between the 4 and the 5 and then it's doable...

Shhhh don't give the answers away!

Ok then

Someone tell me how to do it. Without the measurements for the indent I have NO IDEA

 

[joey1211]

16 x 4 = 64
16 x 5 = 80
20 - (4 + 5) = 11
11 x ? (This is where I get stuck)

 

[Alz_D]

Me too

There's no way of knowing the area, you can't break it down into 3 squares or rectangles then add them all up because we don't know the length of the short horizontal surfaces, we only know that the top is 16m in length, from what I can see anyway?

The vertical line in the indent is easy to work out. But surely we also need the length of the two horizontal lines in the indent? Without that I don't see how its possible. The width of the indent could be any size.

 

[dirtychinchilla]

I can't see how it works either. How deep is the indent? After that, it's all ****.

Does the question tell you the area of the shape?

 

[paradigm]

Unless there is some other key information missing, such as the section of the indent is a regular square.

How is the question written?

 

[Alz_D]

Pretty much exactly like I wrote it out. It's the ninth example of similar shape - all of which are 11 year old easy! It must be an error on the paperwork.

 

[doogs]

The only way to work it out is if you assume the indent is an equal sided square (i.e., 11 x 11).
Other than that the horizontal measurements in the indent are missing

Come on then clever clogs, spit it out.

 

[Alz_D]

If you assume lengths it becomes easy but the way it is drawn the larger length top right is labeled 4 and the smaller one bottom right is labeled 5 so it's clearly not to scale

I'm sure Russell Crowe would have this done already but as he wasn't available last night I thought I'd check with you guys ha ha

Watch them all go quiet
