Yeah, so how the fuck do you solve the area out of this? I already solved the triangel...

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

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.
