Area of a Rectangle - rectangle_area\ This function returns the area of the rectangle with given base and height\

area = base * height

\ Area of a Triangle - triangle_area\ This function returns the area of three given triangle side lengths calculated according to Heron's formula\ (calculate the semiperimeter first, then use that to calculate the area):\

s=(a+b+c)/(2)\ area =\\\\sqrt(s*(s-a)*(s-b)*(s-c))

\ Do not use any built-in method or function for any Python library. Remember that roots are the opposite\ of an exponent. So you can calculate the square root of a number by using the exponent form

n^((1)/(2))

.\ Area of a Trapezoid - trapezoid_area\ This function returns the area of the trapezoid with given base_1, base_2, and height.\

area =(1)/(2)*( base _((

)

1)+ base _((

)

2))* height

\ Area of a Circle - circle_area\ This function returns the area of the circle with the given radius, rounded at two decimal places. Use\ the value 3.1415 for

\\\\pi

.\

area =\\\\pi * radius ^((

)

2)

\ Any area - calculate_area\ This function calls the other functions, based on a string argument: "rectangle", "triangle", or\ "circle". It returns a string that looks like this:\ The area of the triangle is 6.0\ This function takes a total of four arguments, the first one is a string that tells the function which area to\ calculate, and the three other parameters are numeric. In the case of the circle, for example, only the first\ numeric argument is used.\ Test cases\ def main():\ print( rectangle_area(4, 4.5) ) # 18.0\ print( triangle_area(
