Answer:
88168in²
Step-by-step explanation:
:)
 
        
                    
             
        
        
        
9m
It said the sides are 25m (x2) and 9m(x2). The width of a rectangle are shorter than the length so 9m.
        
             
        
        
        
Let us assume the first number = x
Then the second number = 5x -2 
The third number = x + 4
The total number that needs to be divided into three parts is 219
Then we can write the equation as 
x + 5x - 2 + x + 4 = 219
7x + 2 = 219
7x = 219 - 2
7x = 217
x = 217/7
  = 31
Then
First number = 31
Second number = 5x - 2
                           = (5 * 31) - 2
                           = 155 -2
                          = 153
Third number = x + 4
                       = 31 + 4
                       = 35
So the three numbers are 31, 153 and 35. 
        
             
        
        
        
It would be 40n + 7=x!!!
Hope this helps have a good day!!!
