Estimate the area of alberta in square miles. show your reasoning

 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 .

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
