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:
![A_t=\frac{h}{2}(B+b)](https://tex.z-dn.net/?f=A_t%3D%5Cfrac%7Bh%7D%7B2%7D%28B%2Bb%29)
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:
![A_r=lw](https://tex.z-dn.net/?f=A_r%3Dlw)
Wkere "l" is the lenght and "w" is the width.
Then, the apprximate area of Alberta is:
![A=\frac{h}{2}(B+b)+lw](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bh%7D%7B2%7D%28B%2Bb%29%2Blw)
Substituting vallues, you get:
![A=(\frac{(410\ mi-180\ mi)}{2})(760\ mi+470\ mi)+(180\ mi)(760\ im)\\\\A=141,450\ mi^2+136,800\ mi^2\\\\A=278,250\ mi^2](https://tex.z-dn.net/?f=A%3D%28%5Cfrac%7B%28410%5C%20mi-180%5C%20mi%29%7D%7B2%7D%29%28760%5C%20mi%2B470%5C%20mi%29%2B%28180%5C%20mi%29%28760%5C%20im%29%5C%5C%5C%5CA%3D141%2C450%5C%20mi%5E2%2B136%2C800%5C%20mi%5E2%5C%5C%5C%5CA%3D278%2C250%5C%20mi%5E2)
Therefore, the area of of Alberta is about
