For this challenge we are going to use a Python script to calculate the area in square meters of two different flats.

To do so we will write a computer program that will add up all the areas of each room.

Most rooms have a rectangle shape. So we will first define a function that takes two parameters: width and length and return the area of the rectangle using the following formula:

*area = width * length*

Let’s use this formula to calculate the area of this small flat:

#### Challenge #2

The area of a right-angled triangle can be calculated as follows:

*area = width * length / 2*

Add a new function called *getTriangleArea* to return the area of a right-angled triangle using two parameters: width and length.

Use both the *getRectangleArea* and *getTriangleArea* functions to calculate the area of this room:
