Rectangle

Area of rectangle= Length x Width

Perimeter of rectangle = 2 x Length + 2 x Width= 2(length+width)

Square

Area of square= side x side = s2

Perimeter square = 4 x Length of side= 4s

Parallelogram

Area of Parallelogram= Base x Height=b x h

Perimeter of Parallelogram = Sum of length of all sides

Triangle

Area of Triangle

 A=\frac{(base * height)}2= \frac{bh}2

Perimeter of triangle = Sum of all sides

Area of Equilateral Triangle

Equilateral Triangle has all sides equal in length.

Height of equilateral triangle

h= \frac{\sqrt{3}}2 a

Side length = a

Area of equilateral triangle is

A=\frac{\sqrt{3}}4a^2

Area of Circle

Area of Circle 

A =\pi r^2

Circumference of Circle

C = 2 \pi r = \pi d

d= diameter of circle= 2r

Area of Trapezium

Area of trapezium 

A= \frac{(a+b)h}2

Volume of Prisms

Volume of any prism = Base area x Height

Surface area of any prism= Perimeter of base x Height + 2 x area of base

A= PH+ 2B

B=Base area is area of base shape, H= Height of Prism, P= Perimeter of Base

Volume of rectangle prism = Length x Width x Height

Surface

Volume of Cylinder 

V = \pi r^2h

Where r= radius of the base, h= height of cylinder

Surface area of Cylinder

SA= 2\pi rh + 2\pi r^2

Volume of Pyramids

Volume of Any pyramids 

Volume = \frac{1}3 * base area * Height

Volume of Cone

Volume= \frac{1}3 \pi r^2h

Surface area of Pyramids

SA = \frac{P*L}2 + B

Where P= Perimeter of base, L = Lateral height, B= Base area

Surface area of Cone

SA= \pi r^2h +\pi r l

Lateral height (l)

l^2={r^2 + h^2}





Volume of Sphere





V= \frac{4}3 \pi r^3










Surface area of Sphere 





SA= 4\pi r^2
