A triangle is called an equable triangle if its area equals its perimeter. Return `true`, if it is an equable triangle, else return `false`. You will be provided with the length of sides of the triangle. Happy Coding!
def equable_triangle(a,b,c):
    s = (a + b + c)/2
    return (s*(s - a) * (s - b) * ( s - c)) ** 0.5 == 2 * s
def equable_triangle(a,b,c):
    s = (a + b + c)/2
    return (s*(s - a) * (s - b) * ( s - c)) ** 0.5 == 2 * s
