Yeah, so how the fuck do you solve the area out of this? I already solved the triangel, but I dont know how to solve the rectangel. help
Yeah, so how the fuck do you solve the area out of this? I already solved the triangel...
Oh and btw. you are only gonna solve the purple area, not the white.
(8 × 8) - (3 × 3)
8×8 - 3×3
64-9=55
>no right angle indicators
literally impossible
Exam today?

Kill yourself you daft cunt.
8^3 - (3/20)
No i just found this on facebook and since im retarded i couldnt solve it.
Your obviously not autistic.
There is a fucking square there you autistic fuck.
Triangle: (12 * 8) / 2 = 48
Square: 8 * 8 = 64
Hollowed out Square: 3 * 3 = 9
48 + 64 - 9 = 103 cm^2
All the purple area is (8 + 20) * 8 / 2 - 3 * 3 = 103
You don't decompose the trapezoid (or what the outer shape of the purple area is called). A trapezoid with parallels of lengths a and b and height h has area (a + b) * h / 2
Solve the outer square and then the inner square subtract (big-small)
>cm^2
no
151
103 cm is correct
Yes, actually
How do you know it's a square? and aren't autists good at math anyway?
purple shape:
8*8 + (8*12)/2
64 + 48
112
white shape:
let's assume it's square (not shown, so technically this cannot be solved)
3*3
9
purple area:
112 - 9 = 103
>solve the 'area'
>user includes squared centimetres
>no
You are fucking retarded
>8cm by 8cm
>Not a square
Kill yourself
My bad, didn't see the cm in OP's pic
You all fell for the bait.
>3cm by ? cm
>A square
>how
It fucking says 8cm * 8cm
And no, autistic people concentrate intently on very few things. It's not always mathematics.
It can be a rhombus also you dipshit. Check your right angle privilege.
It says cm in the picture so its cm^2
(big purple Square) - (White Square) - (triangle) = area
(20*8) - (3*3) - (12*8/2) = area
If it was a rhombus, the 12cm wouldn't be correct anymore right
that center square is definitely not 3x3. 3 cm wouldn't take up that huge a fucking chunk from a 8 cm square.
i guess you're right
>He thinks the visual size of math drawings matter
laughinggirls.jpg
It is 3*3
are we supposed to assume that is a 3x3 cm square...
>assuming the hollow space is square
No it is 3 * ?
The height is not specified
It being a square is not specified
gb2/math/
what's up Sup Forums?
>making assumptions about the white square height
F, see me after class
It is Just some tetarted math example. And not Quantum physics. It is 3*3. The sides Look like They are The same length, and one is 3cm is Long so The other one is also 3cm.
Obviously not to scale.
The 3cm measure is on the same axis as the 8cm, 12cm and 20cm.
