Step-by-step explanation:
 
        
             
        
        
        
Area of square= s^2
12.25=s^2
take the sqrt(12.25) = 3.5
Perimeter of square = 4s
P=4(3.5)
P= 14 m
        
             
        
        
        
Answer:
c
Step-by-step explanation:

5(2)^2-2(7) = 6
6(7+2)/2 = 27
Therefor the correct answer is the < symbol. 
I hope this helps! :)
 
        
                    
             
        
        
        
AB
 It is indicated in the figure and is valid:
 m AB = 49
 m ABC
 Angle resulting from the following subtraction:
 m ABC = 360-107 = 253
 m BAC
 Angle resulting from the sum of the two angles shown in the figure:
 m BAC = 107 + 49 = 156
 m ACB 
 Angle resulting from the following subtraction: 
 m ACB = 360-49 = 311
