The triangle that is formed by AMB is a 45 45 90 triangle, so meaning the legs are equal. so in can be concluded that AD = MD, since M is the midpoint of CD, then CD = 2AD
CD = 2(6) = 12 cm
so the perimeter is of the rectangle ABCD is
P = 2l + 2w
P = 2(6) + 2(12) 
P = 12 + 24
P = 26 cm
        
                    
             
        
        
        
3x + 6 = 27
step 1. subtract 6 from both sides 
3x = 21
step 2. divide both sides by three to get x alone 
x = 7
