this is a 10th grade question which should be easy but my brain is just a bit malfunctioning tonight 😔

yes ABCD = 20m²

robust peak
#

...that's... not an answer to the question I asked

#

ABCD can have that area regardless of what type of quadrilateral it is.

sudden bobcat
#

are u saying we should ignore the triangle??

robust peak
#

No.

If you want to know what I'm saying, you should read what I'm saying.

Mm it's like take 20- area of flower bed

#

Oh wait

sudden bobcat
#

assume? yes we should 😭

robust peak
#

Are we supposed to assume AD and BC are the same length and parallel, and AB and CD are the same length and parallel?

#

And that angles A, B, C, and D are all right?

robust peak
#

The question doesn't tell us, but it seems like we're supposed to from context, so you probably want to note that assumption.

#

Okay, so what's the formula for the area of a rectangle?

sudden bobcat
#

width x length

signal roost
#

Here

#

X-1=0

#

X=1

sudden bobcat
#

so its gonna be (2+3x)(3+x)=20

signal roost
#

Yep

#

Total length into total breatdth

#

but can u simply move the 20m² to the left?? i mean, u did 6 - 20.. which 6 is a whole number and 20 is with the m²

#

no. move*

signal roost
#

It's equal

signal roost
#

Area in terms of x = area of rectangle

Bro

#

2+3x m * x+3 m

#

So when you multiply

robust peak
sudden bobcat
#

sorry im unable to explain it properly

#

studying indeed tiring 🥹

robust peak
#

Where does the 6 come from?

sudden bobcat
#

guess im going to stop with my revision tonight 🥹🥹 brain started to show 'damage' aka being burned out

robust peak
#

It comes from 2 * 3.

#

2 meters * 3 meters = 6 meters squared.

sudden bobcat
#

ahhhhhh

#

i forgot its in m

#

💔
