please answer correctly no nonsense answers please.

Answer 1

Forgive my Handwriting...

Answer 2

2D

Square

A= s^2
P= 4s

Rectangle

P=2(l+b)
A= l×b

Circle

Peimeter/circumference= 2×pi× radius
area= pi×r^2

Trapezium

Area= 1/2(sum of parallel sides)×height
Perimeter= sum of sides

Rhombus

P= 4s
A= 1/2×diagonal 1× siagonal 2

Parallelogram

P=2(l+b)
A=base × height

3D

Cube

area,

Lsa= 4×s^2
Tsa= 6l^2
Volume= s^3

Cuboid,

Lsa= 2(l+b)h
Tsa= 2(lb+bh+lh)
Volume= l×b×h

Cylinder

Csa= 2×pi×r×h
Tsa= 2×pi×r(r+h)
