Answer:
area of square =length × length ×height 
 =6×6×8
 =288
 
        
                    
             
        
        
        
If you are asking how long the string is or the hypotenuse it would be about 75.89466

I think it's B
 
        
             
        
        
        
The area of a square is 
s • s
We can also write this as
s^2
So, for any side length “s”, we can make a function, A(s), such that 
A(s) = s^2
Now that we have a quadratic equation for the area of a square, let’s go ahead and solve for the side lengths of a square with a given area. In this case, 225 in^2
225 = s^2
Therefore,
s = sqrt(225)
s = 15
So, the dimensions are 15 x 15 in
        
             
        
        
        
Answer:
x= 55
Step-by-step explanation:
The  two angles add to 180 degrees since they form a straight line
2x+70 =180
Subtract 70 from each side
2x+70-70=180-70
2x= 110
Divide by 2
2x/2 = 110/2
x= 55
