What are formulas for area and perimeter for all shapes.

Perimeter formula

○Circle2 × pi × radius

□Square4 × side

⎕Rectangle2 × (length + width)

▱Parallelogram2 × (side1 + side2)

△Triangleside1 + side2 + side3

⬠Regular n-polygonn × side

⏢Trapezoidheight × (base1 + base2) / 2

⏢Trapezoidbase1 + base2 + height × [csc(theta1) + csc(theta2)]

⬭Ellipse4 × radius1 × E(k,pi/2)

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

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

Area of Rectangle

Area = l × wl = length

w = width

Area of Square,

Area = a2,

a = sides of the square

Area of a TriangleArea = 1/2 b×hb = base

h = height

Area of a Circle,

Area = πr2

, r = radius of the circle

Area of a TrapezoidArea = 1/2 (a + b)ha =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:

Parallelogram2(Base + Height)

Triangle

a + b + ca,

b and c being the side lengths

Rectangle2(Length + Width)

Square4aa =Length of a side

Trapezoida +b+c+da, b, c, d being the sides of the trapezoid

Kite2a + 2ba = Length of the first pair of equal sides

b = Length of the second pair of equal sides

Rhombus4 x aa = Length of a side

Hexagon6 x aa = Length of a side

i believe the answer is 323 ft
