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  .

Answer:
$980
Nvm you have to multiply 98 by 10 since there are 10 participants. :)
Step-by-step explanation:
Well, first we wanted to find how much the morning classes cost together. You have to $28 multiplied with 75/100. I am multiplying it with 75/100 instead of 25/100 because the discount cuts off the 25% and the 75% is what you still have to pay. This will give you 2100/100 which is $21. Now you have to multiply $21 with 2 since there are two morning classes. $21 x 2 equals $42. Total for Morning Classes is $42. 
Now the other two classes don't have a discount. So all you have to do is $28 x 2 or $28 + $28. This gives you $56. Total for The Other Classes is $56. 
Last Step:
Total for Morning Classes + Total for the Other Classes = $56 + $42
                                                                                              = $98
Hope that helped! :)
