Functions for calculation of the area and perimeter of the figure

Formulas

Area

• Circle: S = πR²
• Rectangle: S = ab
• Square: S = a²
• Triangle: S = a*(h / 2)

Perimeter

• Circle: P = 2πR
• Rectangle: P = 2a + 2b
• Square: P = 4a
• Triangle: P = a + b + c

Functions

Circle

• area: takes a number r, returns the area of a circle with radius r

• • Function: area(r)
• • Example: area(2) = 12.5836

• perimeter: takes a number r, returns the perimeter (circumference) of a circle with radius r

• • Function: perimeter(r)
• • Example: perimeter(10) = 62.918

Rectangle

• area: takes numbers a and b, returns the area of a rectangle with given lenght of a and b

• • Function: area(a, b)
• • Example: area(5, 10) = 50

• perimeter: takes numbers a and b, returns the perimeter of a rectangle with given lenght of a and b

• • Function: perimeter(a, b)
• • Example: perimeter(4, 4) = 16

Square

• area: takes a number a, returns the area of a square with the given length of a and b

• • Function: area(a)
• • Example: area(7) = 49

• perimeter: takes a number a, returns the perimeter of a square with the given length of a

• • Function: perimeter(a)
• • Example: perimeter(12) = 48

Triangle

• area: takes numbers a and h, returns the area of a triangle with the given lenght of a and h

• • Function: area(a, h)
• • Example: area(2) = 10

• perimeter: takes numbers a, b, and c, returns the perimeter of a triangle with the given lenght of a, b and c

• • Function: perimeter(a, b, c)
• • Example: perimeter(1, 2, 3) = 6
