It's the long awaited sequel to my first Geometry Problem style video! Hope you all enjoy and let me know if you find any other methods to solving the problem 🧠

I didn't understand why expanding the brackets in the second section resulted in 24y. other than that great video and well explained.

@@AngusCalvert The (12 + y)² is a binomial formula and gets solved like this: (a + b)² = a² + 2ab + b² a in this case is 12 and b is y. The full way to solve it is: (a + b)² = (a + b) * (a + b) Here you solve it via the 'FOIL' method, aka 'First, Outer, Inner, Last - you multiply first the two first variables of the respective brackets, then the two outer variables, then the two inner variables, and then the last two variables of each respective bracket: (a + b) * (a + b) = a² + a*b + a*b + b² You can sum up the two [a*b] parts and get a² + 2ab + b² Now in our specific case, it'd go as follows: x² = (12 + y)² = 12² + 2*12*y + y² = 144 + 24y + y²

@@Aghul thank you very much. I now understand double brackets and how to expand them

208 + 64 + 16 = 288 (total area of square without the green one) Now we try squaring whole numbers 17²= 289 (illogical to be our full square) 18²=324 (is probably the area of our full square) 19²=361 (might be) So we take our added up area and subtract it from our potential full square 324 - 288 = 36 (the area of our green square) Now we know the blue is 16 in area And Red is 64 Obviously the green is somewhere in between and 36 is definitely between them so it's 36

I'm working through some math problems right now, how convenient!

@saeedwrld22 9 месяцев назад

I solved the problem since the start of the video and stay to enjoy some good asmr

@ASMRMaths 9 месяцев назад

Awesome!

@geneash8547 9 месяцев назад

I just saw that the green box was in between them and red is 8x8 and blue is 4x4 so green is 6x6 and I added them all together

@Waiter1986 9 месяцев назад

not how it really works. could’ve ended up with the wrong answer just by guessing it lol

@7venxce 9 месяцев назад

there's always a possibility that the green square is not a square that has sides with integer values (for example 5.5, 5.9, etc). proving it with a solution will always be the best :))

Enjoyed working on this prob, it was kinda easy but really enjoyed it!

@Pillowkasmr 9 месяцев назад

You whisper is super relaxing and your channel super original! I also do ASMR videos (but not about mathematics ahah)

@ireallylovelunchtime 9 месяцев назад

I just guessed the area of the green box because of the similarities in the shapes 😂

@ASMRMaths 9 месяцев назад

That's really good initiative. It's called mathematical approximation. Here you were able to approximate the area of the green box due to other areas of maths as you mentioned! Love to hear it

@WinterFlare 9 месяцев назад

Lol I took a look at it and was like the green box is 36 yeah? The gap between the height of the blue square to the green square is the same as the height from the green to red square. So I just assumed it was a gap of 2.
