Hello,
10 is not a digit!
Let' a ,b ,c the 3 digits 
Numbers are 
10a+b
10a+c
10b+c
10b+a
10c+a
10c+b
sum = 22a+22b+22c=22(a+b+c)
sum /(a+b+c)=22
        
             
        
        
        
Step-by-step explanation:
solution.
Let S represent side of the equilateral triangle.
 
perimeter of equilateral ∆ =3×S
Therefore,if we let width to be represented by W
 Width of rectangle=W
 Length of rectangle=2W
one side of equilateral triangle= W+8
Therefore after analysing the question, the true statement is; The length of the rectangle is 2W
