Answer:
   The flag of Switzerland is square.
Step-by-step explanation:
Only Switzerland has a flag that is square.
The measurements can be anything convenient. The aspect ratio (height to width) is 1 : 1. 
When the flag is displayed next to a rectangular flag, it should have the same area as the rectangular flag. (This will mean the Swiss flag side length is the geometric mean of the rectangular flag dimensions.)
_____
Sometimes, the measurements of the flag are chosen to go with the height of the flagpole. The US flag is customarily displayed on a pole 3-4 times as long as the flag is long. That is, the diagonal of the flag is about 0.28 to 0.38 times the pole height.* I could not find comparable information about the Swiss flag.
____
* The diagonal is of interest when the flag is hanging down along the pole, not flying in the wind.
 
        
             
        
        
        
Length: 
60% of 6 is 3.6
3.6 x 6 = 21.6 
Width: 
150% of 5 is 7.5 
7.5 x 5 = 37.5 
So her mothers garden should be 21.6 feet in length, and 37.5 feet in width. 
        
                    
             
        
        
        
6n-8<5n  decreased means subtract
n-8<0
n<8
 
        
             
        
        
        
So this is basically a ratio and the form I use to solve these is
Is. = %
Of. 100
So we're looking for 5% of the 350,000 which will be x
X. = 5
350000. 100
Cross multiply 
100x=1750000
Divide by 100
X=17500
