Answer:
All angles in a rectangle are congruent, because in a rectangle, all angles are 90 degrees. 
 
        
             
        
        
        
Area of square =6*6= 36 cm^2
Area of trapezoid =1/2( base1+base2)*height
base 1=7
base2=21-6=15
height=6
Area of trapezoid =1/2( 7+15)*6= 66 
whole area = area of square + area of trapezoid= 36+66=102

Answer:
D one solution.
Step-by-step explanation:
It's linear. It is going to have at most 1 solution
8 + x/6 = x/6 - 4 + 5x/12                  Subtract x/6 from both sides
8 = -4 + 5x/12                                   Add 4 to both sides
8+4 = 5x / 12                                    Combine
12 = 5x / 12                                      Multiply both sides by 12
12 * 12 = 5x * 12 / 12                         Cancel
144 = 5x                                            Divide by 5
144/5 = 5x/5
28.8 = x
 
        
             
        
        
        
1 because it can't be reflected over more than one line to be the same
