Equation: 99 + 45x, with x as how many ever months.
After five months: 
99 + 45(5) = 99 + 225 = $324.
        
             
        
        
        
Rotate one of them so the right angle is in the same orientation as the other one.
1. AB = DE
2. CB = FE
3. AC = DF
4. Compare the length of two known sides: cb and EF
CB = 3 and EF = 8
8/3 = 2 2/3 scale factor
5. Ab is side de. Multiply the length of ab by the scale factor:
4 x 2 2/3 = 10 2/3
6. FD = sqrt ( 10 2/3^2 + 8^2)
FD = 13 1/3
 
        
             
        
        
        
Answer:
40
Step-by-step explanation:
75% divided by 3 since its 3/4 of 100 
do the same to 30
 
        
             
        
        
        
The dimensions would be 29 by 29.
To maximize area and minimize perimeter, we make the dimensions as close to equilateral as possible.  
Dividing the perimeter by the number of sides, we have
116/4 = 29
This means that both length and width can be 29.
