Point m is the midpoint of AB. if the coordinates of m (2,8) in the coordinates of A (10, 12) are the coordinates of B this is your answer 4/8
        
                    
             
        
        
        
Answer:
7 or 
Step-by-step explanation:
Each triangle has the surface area of 1.5, because 1  3 = 3 / 2 = 1.5. You divide by two because it is half a rectangle instead of a full one. You multiply by four which would get you 1.5
 3 = 3 / 2 = 1.5. You divide by two because it is half a rectangle instead of a full one. You multiply by four which would get you 1.5  4 = 6. The square in the middle has the surface area of 1 because 1
 4 = 6. The square in the middle has the surface area of 1 because 1  1 = 1. So you would get 7.
 1 = 1. So you would get 7.
