Geometric library

Description

A geometric library written using Python that contains functions to calculate area and perimeter of different geometric figures:

• Square
• Rectangle
• Triangle
• Circle

Math formulas

Area

• Circle: S = πR²
• Triangle: S = ah
• Rectangle: S = ab
• Square: S = a²

Perimeter

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

Functions

Circle

Area(r)

Function area(r) gets a number (radius) and returns a number (area value of the circle with the given radius).

from circle.py import area

r = 5
value_area = area(r)
print(value_area)

The code will print 78.53981633974483

Perimeter(r)

Function perimeter(r) gets a number (radius) and returns a number (perimeter value of the circle with the given radius).

from circle.py import perimeter

r = 5
result = perimeter(r)
print(result)

The code will print 31.41592653589793

Triangle

Area(a, h)

Function area(a, h) gets two numbers (side of the triangle and the height to this side) and returns a number (area value of the given triangle with such side and such height).

from triangle.py import area

a = 3
h = 6
result = area(a, h)
print(result)

The code will print 9

Perimeter(a, b, c)

Function perimeter(a, b, c) gets three numbers (sides of the triangle) and returns a number (perimeter value of the triangle with such sides).

from triangle.py import perimeter

a = 3
b = 4
c = 5
result = perimeter(a, b, c)
print(result)

The code will print 12

Square

Area(a)

Function area(a) gets a number (side of the square) and returns a number (area value of the square with such side).

from square.py import area

a = 5
result = area(a)
print(result)

The code will print 25

Perimeter(a)

Function perimeter(a) gets a number (side of the square) and returns a number (perimeter value of the square with such side).

from square.py import perimeter

a = 5
result = perimeter(a)
print(result)

The code will print 20

Rectangle

Area(a, b)

Function area(a, b) gets two numbers (sides of the rectangle) and returns a number (area value of the given rectangle with such sides).

from rectangle.py import area

a = 5
b = 6
result = area(a, b)
print(result)

The code will print 30

Perimeter(a, b)

Function perimeter(a, b) gets two numbers (sides of the rectangle) and returns a number (perimeter value of the rectangle with such sides).

from rectangle.py import perimeter

a = 5
b = 6
result = perimeter(a, b)
print(result)

The code will print 22
