First we are going to find divided by 100 and multiply 20 is equal to four. 
We are gonna use x to represent this number.
x/100 * 20 = 4 
Solve for x 
Therefore x = 20cm 
Now that we found x the side of the larger square we are gonna find the area which is side^2.
20 * 20
Therefore the area of the larger square is 400cm^2
        
             
        
        
        
Answer:
$51.70 is the original price 
Step-by-step explanation:
Step 1: 
Turn 40% into a decimal which makes it 0.40 
ex. 50% would be 0.50, 5% would be 0.05 etc. 
Step 2:
Put the numbers into this formula: Original Price (x) - Percent Off times Original Price = Sales Price 
x - 0.40x = 31.02  this is basically 1x - 0.40x = 31.02 so,
Solving the left side of our equation gives us 1x - 0.40x = 0.60x 
so now you have: 0.60x = 31.02
Step 3: 
Divide both sides by 0.60 which gets x by itself and gives us the original price which is $51.70
