32 cm^2

>>735471677
This is impossible to solve without knowing at least some angles or lenghts.

36

easy
since each quarter's sides are 11 cm => ? = 11 * 11 = 121 cm2

>>735472444
>since each quarter's sides are 11 cm
how do you know that?

>>735472445
Explain then.

>>735472444

How do you know they lenght 11?

>>735472444
Please tell me you aren't using those little black lines for the number 11 lmao.

Im also going to guess 28 since it seems to be the most sense for everything to add up to 90 squared and the muster shape is close to the size of the 32.

But how exactly do you solve without one single straight line measurement...? Am I supposed to print out and use a ruler...?

>>735472638
i thought this too

100...easy pz

>>735471677
Each point is 2,236068

If we assume it is square and not rectangle and we also assume it's 10 x 10 then the answer is 32cm2

>>735473330
Why are you assuming it's 10*10?

>>735473330
You don't need to assume that it's a square, that much is explicit in the image.

>>735473377
Because I find it easier to add up to round numbers.

>>735473448
That's a pretty fucking impossible square, anon.

>>735473448
Hi, welcome to 4chan!
Everyone is a faggot here so there is a very high possibility that, that "square" is infact 9.9 x 10.1

23?

Let 2x = the length of a side and (-a, -b) are the coords of the cross-section point with respect to the centre of the square. The equations we can form are:

x(x-a)+0.5b(x-a)+0.5a(x+b)=20
(x-a)(x-b)+0.5b(x-a)+0.5(x-b) = 16
x(x+a)+0.5b(x+a)-0.5a(x+b)=32
4x^2=20+16+32+x^2+ab-0.5b(x+a)-0.5a(x-b

>>735473330
Then figure x should be equal square like the one above.

>>735473581
Is there anyone with paper and some knowledge to prove this? I just guess here (then side if square will be 9).

its 23

>>735473570
so x+y = 28

>>735472638
>>735472341
>>735473448
I'm pretty sure those are equals signs.

>>735473581
No the answer is 28. Try using the image I posted and create

>>735471677
32m2
Its a square, so its 100m2 in total. 32m2 is missing.

>>735473853
Right. Pizza law works easier here.

ignorant neets thinking of a way to understand maths

>>735473853
but x + y = 8 + 16 = 24

>>735473570
>>735473570
a+b=20
b+y=32
y+x=?
x+a=16

y=32-b and x=16-a therefore 32-b+16-a=?
so 48-b-a=? rearranging 48=?+a+b but a+b=20
therefore 48=?+20 therefore 28=?

Impossible to solve

>>735473853
the answer is 24 because half of 16 (x) and half of 32 (y) is 24
otherwise explain how you get 28?
>>735473570

>>735473570
Guess I was wrong, the answer is Ctrl + V

a,b,x,ya,b,x,y are areas of their triangles. We can then construct a system of equations:

a+x=16a+x=16
a+b=20a+b=20
b+y=32b+y=32
and see

a+x+b+y=48a+x+b+y=48
a+x+b+y−a−b=x+y=48−20=28a+x+b+y−a−b=x+y=48−20=28
Which is our desired result.

>>735474376
Possible. Check https://en.wikipedia.org/wiki/Pizza_theorem?wprov=sfla1

>>735473570

For the idiots:

a+b = 20
a+x = 16
b+y = 32

So:
a = 16 - x
b = 32 - y

Leading to:
a + b = 16 + 32 - x - y = 20

Finally:
x + y = 16 + 32 - 20 = 28

>>735474531
lol, this has nothing to do with the pizza theorem because this is not a circle. You use trigonometry: https://en.wikipedia.org/wiki/Median_(geometry)#Equal-area_division

>>735471677
Just by looking at it for 2 min and not doing any actual calculations I am going to say 28 cm^2. This was derived assuming each line begins exactly in the middle of the sides. Anyone has the method?

>>735475453
Perhaps you should learn the difference between a correct result and a correct solution before calling other people dumb, faggot.

Nice pretending you didn't read the thread.

Brilliant refutation. Why don't you try publishing a math paper in which you give the result of your calculations but not the calculations themselves, and then see if anyone agrees that you've "solved" the problem. "Hey, I've solved the Riemann hypothesis! Won't give you the calculations, though." Go back to math class, faggot.

OR, INSTEAD OF DOING AUTISMO MATH, JUST FUCKING LOOK AT THE IMAGE

>>735471677

20 + 32 + 16 = ?

It equals 68.

A little bird tells me the total area is 100 cm^2, not some autistic number.

And the shown areas comprise 68% of the total? Well, it seems logical.

Hence, 28cm^2 is in all likelihood the answer.

The old pizza problem...what is this, year 9 geometry?

Someone has posted an image I see.

a+x=16
a+b=20
b+y=32
It can be seen that:
a+x+b+y=48 by adding the top right and bottom left areas.
We know a+b=20 from the top left area, therefore x+y=48-20=28

This is a false square. The "=" markings on each "leg" indicates that the length of each leg (x) is the same. And lets say starting with the 16cm2 figure that would equate to sqrt(16)giving us the x value of 4. 4x4 may equal 16 but does not equal to the rest of the areas aka your square is false

>>735475915
100-68=28 now?

Shit, back in my day that equalled 32. What a new and exciting future awaits with this new arithmetic.....

>>735476431
the truth is when youre 30+ years old you forget everything from school as its not used daily

>>735476786
I still use a lot of highschool math every day, but usually because as an engineerfag and many of the first principles shit with triangles is super useful.

For people who have not solved it yet, the trick is to understand the marking of the sides and dividing sections into triangles

I still haven't figured out why x / 0.7 = 30% and why x X 1.3 = not 30% ?

>>735477201
there are exceptions like computer maniacs

>>735471677
so i've almost finished first year to get bachelor's degree and i have no idea, i've read most of the thread and wtf am i dumb?

>>735474461
look closer, it's not half.

>>735471677
Each side is split into two things of 11.
11*11*2=242
242-(20+32+16)=174
So it is 174. Bad scaling, but it's correct.

>>735478091
lol wut?

>>735478091
nigger if something is like 25cm2 its sides are like 5cm

>>735472006
I guess this thing will need formula of area by degree, because total ange on the center bis 360. Honestly i forget the formula.

i have no idea how to do this but let me know if this is the right track...they are give the area but you need the length and width..could you find length and width with information given.. if so, you could find the missing peace by subtracting the known area from the missing area..
