No link
If I keep school aside, I study by my own and your videos assist me which I'm really thankful for. Also the way you explain things and often repeat what you expounded without any student asking you to, that way there's no need to reverse the videos of yours to understand what we might haven't on first listen. I greatly appreciate your work.
I've never commented under your channel but today I wanted to just comment down each thing I've been storing to say at once.
Thank you sir! Saying this on the behalf of every student of yours.

In the 3rd part can we use trapezoid formula to find area?
Ya but we first have to find h
@@t_c7710 we can also find 'h' but it's more easier to make 3 triangle and do it
Yes for that you have to break 2 cm line into 3 parts
.5,.5,1 cm then take Base of triangle .5 cm and find the height then put it in trapezium s area
Yes
@@prachisharma733 i am in class 10th now prachi 😂
In First Part 1:25 There was no need to find triangle with Heron's Formula it can be found directly by 1/2*base*height as it is iscocelse triangle

How do you know that 🤨

Sir how. to find root value
By long division , don't follow any trick only long division method to find any root.
link in description 😂😂
By multiple of same number 2 times and we got the value of root value
For eg:- √9 = 3
√9= 3 x 3 so its value is 3 cm or m²

in 1st part why another triangle is 5cm
Coz this was isosceles triangle
B/c they are isoceles triangle whose both side are equal
As aeroplane is a symetrical object so both sides must equal....
Hope you got it...

Thank you sir mujhe bilkul samaj nahi a Raha tha ye long questions ap ki vedio dekh Kar Kamal ho gya thanks for sir
sir 2.48 cm^2 is not the area in 1st side because 0.75 x 3.3 = 2.47 (according to the calculator)
Do it on paper calculators mostly provide information thats we dont need
You are wrong because this value is 0.75 × 3.31.
Not this 0.75 × 3.3
Dusaro ko galat kehana sa pehala thik sa dekha lana chahiye
Aapki video dekhta hu tb motivation milta hai ki future mai kuch bne... Head.... Keep it up sir.... Don't stop.... 👍🥰 *STAY HEALTHY*
Sir good explanation app hmra schl pa aa jayeya
