what are formulas for area and perimeter for all shapes.​

Sagot :

Answer:

Perimeter formula

○ Circle 2 × pi × radius

□ 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)]

⬭ Ellipse 4 × radius1 × E(k,pi/2)

E(k,pi/2) is the complete elliptic integral of the second kind

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

Answer:

Area Formulas :

Area of Rectangle

Area = l × w l = length

w = width

Area of Square,

Area = a2 ,

a = sides of the square

Area of a Triangle Area = 1/2 b×h b = base

h = height

Area of a Circle ,

Area = πr2

, r = radius of the circle

Area of a Trapezoid Area = 1/2 (a + b)h a =base 1

b = base 2

h = vertical height

Area of Ellipse ,

Area = πab ,

a = radius of the major axis

b = radius of the minor axis

Step-by-step explanation:

perimeter formula:

Parallelogram 2(Base + Height)

Triangle

a + b + c a,

b and c being the side lengths

Rectangle 2(Length + Width)

Square 4a a =Length of a side

Trapezoid a +b+c+d a, b, c, d being the sides of the trapezoid

Kite 2a + 2b a = Length of the first pair of equal sides

b = Length of the second pair of equal sides

Rhombus 4 x a a = Length of a side

Hexagon 6 x a a = Length of a side
