At timeframe 10:31 why do you square both terms, the x^4 and x, I understand the x^4 but why square the other? Ain't we supposed to follow the formulae a^2+ab+c?
Im confused we all no P = l+b and area is l×b ... so in this case we know its a square so l=b ... so instead of l+b we can say x+x cos theyre the same ... so if they give us the perimeter of the small square cant we just say 12 = x+x 12=2x therefore x=6
I’m actually starting to enjoy maths now.
You welcome more light

You can work it that way but you but use again the concept of x^2
Yes but what's the main reason using it in this case scenario?
@cliffortphophi7119 remember there are different methods. There I used a better approach so get used even if they change the Exponents to Fractions
for the word equation I just used 4(x+1/2x)-2x=12
Is it giving the same answer

12=2x therefore x=6
P=2(l+b)
hell yeah, got 1.3 right first time
