Write a program in Python that prompts the user for information (radius, side, height, width, etc) about at least three geometry shapes.
Possible geometry shapes: circle, ellipse, rectangle, square, equilateral triangle, right triangle, isosceles triangle, triangle, parallelogram, rhombus and trapezoid.
Use the information to:
– calculate the areas of these shapes;
– print the areas;
– print the sum of the areas;
– print the average of the areas;
– print the larger of the areas;
– print the smaller of the areas.
Hint: Python defines max and min functions that accept a sequence of values, each separated with comma.
Show the results on screen.
Remember: the user will only see what is on screen not what is inside the code. So, use clear and explanatory information.
For the coding, use:
– in-program comments
– logic
– accuracy
– efficiency

# Reading circle data
radius = float(input(“n Enter radius of a circle: “));
# Creating Circle Class object
circleObj = Circle(radius);
# Getting area of circle
circleArea = circleObj.area();
# Reading square side
side = float(input(“nn Enter square side: “));
# Creating Square Class object
squareObj = Square(side);
# Getting area of square
squareArea = squareObj.area();
# Reading rectangle data
width = float(input(“nn Enter Rectangle width: “));
height = float(input(“nn Enter Rectangle height: “));
# Creating Rectangle Class object
rectangleObj = Rectangle(width, height);
# Getting area of rectangle
rectangleArea = rectangleObj.area();
# Storing all Areas in to a list
areas = [circleArea, squareArea, rectangleArea];
# Printing areas
print(“nnnn Circle Area: %.2f ” %(circleArea));
print(“nn Rectangle Area: %.2f ” %(rectangleArea));
print(“nn Square Area: %.2f ” %(squareArea));
# Printing results
print(“nn Sum Of areas: %.2f ” %(sum(areas)));
print(“nn Average Of areas: %.2f ” %(sum(areas)/float(len(areas))));
print(“nn Larger area: %.2f ” %(max(areas)));
print(“nn Smaller area: %.2f nn” %(min(areas)));
# Calling main function
main();
