The formula for the area of a square of side s is A = s^2.
Then s^2 = A, and s = +√A.
Here, the approx. side length is s = +√(75 m^2), or 8.7 m
 
                                
             
                    
              
              
                
                
Area of square = a^2
so
a^2 = 75
a = √75
As you know √64 = 8 and and √81 = 9
√75 is between 8 and 9, So it's is closest to 8
