Question

Equilateral Triangle Class EqTri Write a class that has several functions related to an Equilateral length : float Triangle. The constructor shouldgetArea): float accept a one parameter for the +getPerimeter): float length (which is the same for all 3+float-0 : float sides in an equilateral triangle) + _str) string -str--() method should return a string such as "Rectangle (Area:50)" float) method should return the area (Same functionality as getArea) Math (area- length?, perim/circum 3 length)

Using python 3.x to solve this problem.

Answer 1

class EqTri:
    def __init__(self, length=0.0):
        self.length = length

    def getArea(self):
        return (3**0.5 / 4) * self.length ** 2

    def getPerimeter(self):
        return 3 * self.length

    def __str__(self):
        return 'EqTri (Area:' + str(self.getArea()) + ')'

    def __float__(self):
        return float(self.getArea())


t = EqTri(5)
print('Area = ' + str(t.getArea()))
print('Perimeter = ' + str(t.getPerimeter()))
print(t)
print(float(t))
