Perimeter Area Volume Formulas


Perimeter formula

Square
4 * side
Rectangle
2 * (length + width)
Parallelogram
2 * (side1 + side2)
Triangle
side1 + side2 + side3
Regular n-polygon
n * side
Trapezoid
height * (base1 + base2) / 2
Trapezoid
base1 + base2 + height * [csc(theta1) + csc(theta2)]
Circle
2 * pi * radius
Ellipse

k = (1/radius1) * sqrt(radius12 - radius22)

Area formula

Square
side2
Rectangle
length * width
Parallelogram
base * height
Triangle
base * height / 2
Regular n-polygon
(1/4) * n * side2 * cot(pi/n)
Trapezoid
height * (base1 + base2) / 2


Circle
pi * radius2
Ellipse
pi * radius1 * radius2


Cube (surface)
6 * side2
Sphere (surface)
4 * pi * radius2
Cylinder (surface of side)
perimeter of circle * height
