Answer: About
Step-by-step explanation:
The missing figure is attached.
Notice in the first picture that Alberta has a complex shape.
You can calculate the area of a complex shape by decomposing it into polygons whose areas can be calculated easily.
Observe the second picture. Notice that it can be descompose into two polygons: A trapezoid and a rectangle.
The area of the trapezoid can be calcualted with the formula:

Where "h" is the height, "B" is the long base and "b" is short base.
And the area of the rectangle can be found with the formula:

Wkere "l" is the lenght and "w" is the width.
Then, the apprximate area of Alberta is:

Substituting vallues, you get:

Therefore, the area of of Alberta is about
