i beg someone helps cuz i havent slept for 20 hours i cant think this one through ibr pls

i think im going right ibr

[knotty dock]

how come u havent slept for 20 hours?

[knotty dock]

i believe thats correct but the end isnt -ab√2. its just -2ab because b√2 multiplied by a√2 is -2ab

and to work out the diagonal length of the rectangle u do pythagorus. (a+b√2)² + (b-a√2)² = c²

[queen anchor]

oh SHIT YHH

[queen anchor]

yeh i haven't attempted that one yet

[queen anchor]

grind it real bro

[knotty dock]

Yeh now just group the terms with root 2 together

[queen anchor]

im actually stupid what the fuck

of fucking course man

im too tired mayn

is that it them

[queen anchor]

-ab + (b²-a²√2)

that correct then yh?

[queen anchor]

@native iron part b correct yh?

[knotty dock]

diagonal length is a^2 + b^2 = c^2?? if so then i got √(3a^2 + 3b^2)

so yeh u are correct
