Answer:
It can be decomposed into the following simplest shapes:
Two Rectangles and one Triangle.
The area is 
Step-by-step explanation:
You can observe in the picture attached that it can be decomposed into the following simplest shapes:
Two Rectangles.
One Triangle.
The area of the a rectangle can be found with:

Where "l" is the length and "w" is the width.
You can identify in the picture that:

Substituing values, you get that the areas of the rectangles A and B are:

The formula for the area of a triangle is:

Where "b" is the base and "h" is the height.
In this case:

Then, its area is:

Then, the total area of carpet that Valerie needs for her project is:
