Functions

circle.py

area(r)

• Uses math.pi as an approximate value of π
• Takes r (float) - the circle radius length
• Returnes the area of a circle with given radius length (float)
• Example: print(area(1)) -> 3.141592653589793

perimeter(r)

• Uses math.pi as an approximate value of π
• Takes r (float) - the circle radius length
• Returnes the perimeter of a circle with given radius length(float)
• Example: print(perimeter(1)) -> 6.283185307179586

rectangle.py

area(a, b)

• Takes a, b (float) - the rectangle width and height lengths
• Returnes the area of a rectangle with given side lengths (float)
• Example: print(area(2.1, 3)) -> 6.3

perimeter(a, b)

• Takes a, b (float) - the rectangle width and height lengths
• Returnes the perimeter of a rectangle with given side lengths (float)
• Example: print(perimeter(2.1, 3)) -> 10.2

square.py

area(a)

• Takes a (float) - the square side length
• Returnes the area of a square with given side (float)
• Example: print(area(1.5)) -> 2.25

perimeter(a)

• Takes a (float) - the square side length
• Returnes the perimeter of a square with given side length (float)

triangle.py

area(a, h)

• Takes a, h (float) - the triangle side and the corresponding height lengths
• Returnes the area of a triangle with given side and height (float)
• Example: print(area(2, 1.5)) -> 1.5

perimeter(a, b, c)

• Takes a, b, c (float) - the triangle side lengths
• Returnes the perimeter of a triangle with given side lengths(float)
