Write a class that has several functions related to an Equilateral Triangle. The constructor should accept a one parameter for the length (which is the same for all 3 sides in an equilateral triangle).

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))
