Answer:
A = 83.5m^2
Step-by-step explanation:
9 * 19 = 171m for the complete rectangle
9 - 4 = 5
5 * 19 = 95
95 / 2 = <u>47.5m</u> for the triangles
9 * 4 = <u>36m</u>
36 + 47.5 = <u>83.5m</u>

Here is a simple way we can do this.
We have six blanks.
__ __ __ __ __ __
Now, we have 13 possible options to fill in blank number one.
13 __ __ __ __ __
Now we have 12 possible options to fill in blank number two because one person has already been chosen.
13 12 __ __ __ __
Now we have 11 possible options for blank number three.
13 12 11 __ __ __
Now we have 10 possible options for blank number four.
13 12 11 10 __ __
And so forth until we get:
13 12 11 10 9 8
Now we just have to multiply the numbers all together.
13 * 12 * 11 * 10 * 9 * 8
is equal to:
1235520 ways.
        
             
        
        
        
First divide 3.5 by 2 which equals 1.75. Then do 1.75*3 which equals 5.25. So he drinks 5.25 liters in one hour.
        
                    
             
        
        
        
Answer:
5√2
Step-by-step explanation:
<u>Finding</u><u> </u><u>distance</u><u> </u><u>:</u><u>-</u><u> </u>
- d = √{ ( 1 -6)² + (4+1)²}
- d = √{ -5² + 5² }
- d = √{ 25 + 25} 
- d = √50 
- d = 5√2
