# Note : A trapezoid is a quadrilateral with two sides parallel. The trapezoid is equivalent to the British definition of the trapezium. An isosceles trapezoid is a trapezoid in which the base angles are equal so.
Test Data : 
Height : 5
Base, first value : 5
Base, second value : 6
Expected Output: Area is : 27.5

base_1 = 5  
base_2 = 6  
height = float(input("Height of trapezoid: "))  
base_1 = float(input('Base one value: '))  
base_2 = float(input('Base two value: '))  
area = ((base_1 + base_2) / 2) * height  
print("Area is:", area)
