Parallelogram- b×h. 2(h+b)
Semicircle-. ½πr². πr+d
Trapezium-. ½(a+b)h sum of all 4sides
Quadrilateral-½×d×(h¹+h²) sum of all 4sides
Rhombus-½×d¹×d² or b×h 4×a

Anyone here for 2023 final examination ?? 💀 who are trying to study before hand but are probably gonna watch 1 video and be proud enough to take a break for 5 days ?? 💀

"Perimeter "
1) perimeter of square=4a
2) perimeter of rectangle=2(l+b)
3) perimeter of triangle=a+b+c
4) perimeter of circle =2πr
5) perimeter of semi circle =πr
6) perimeter of parallelogram=2(a+b)
7)regular pentagon = 5a
8)Irregular shape =a+b+c+d+e+f+...sum of all sides
9)curved shape =length of a
"AREA"
1}area of square = a sq.
2}area Of rectangle=l×b
3}area of triangle = bh/2
4}area of circle = π r sq
5}area of trapesium =h/2 (a+b)
6)area of rhombus=1/2 x d1(d2/2 + d2/2

1)cube
TSA = 6a sq
Volume= a cube
2)TSA = 2(l×b + l×h+b×h)
Volume = l×b×h
LSA = 2h (a+b)
3) cylinder
TSA = 2πr(r+h)
LSA= 2πrh
Volume =πr sq.h

never imagined I would say this but "maths Class could be really interesting, but that too when your teacher is like you, ma'am"
Edit: OMG I never thought this comment will get so much likes, I never got them. THANKYOUUU!!!!
