Answer:
57 units^2
Step-by-step explanation:
First find the area of the triangle on the left
ABC
It has a base AC which is  9 units and a height of 3 units
A = 1/2 bh = 1/2 ( 9) *3 = 27/2 = 13.5
Then find the area of the triangle on the right
DE
It has a base AC which is  6 units and a height of 1 units
A = 1/2 bh = 1/2 ( 6) *1  = 3
Then find the area of the triangle on the top
It has a base AC which is  3 units and a height of 3 units
A = 1/2 bh = 1/2 ( 3) *3  = 9/2 = 4.5
Then find the area of the rectangular region
A = lw = 6*6 = 36
Add them together
13.5+3+4.5+36 =57 units^2
 
        
                    
             
        
        
        
Answer:
- 321 adult tickets
- 227 child tickets
Step-by-step explanation:
This sort of problem is easily solved by defining a variable to be the quantity of the higher-value contributor. Here, we can let x represent the number of adult tickets. Then total revenue is ...
   6.50x +3.50(548-x) = 2881
   3x +1918 = 2881 . . . . . . . . . . . . eliminate parentheses, collect terms
   3x = 963 . . . . . . . . . . . . . . . . . . subtract 1918
   x = 321 . . . . . . . . . . . . . . . . . . . . divide by 3
   548-x = 548 -321 = 227 . . . . . .number of child tickets
321 adult tickets and 227 child tickets were sold.
