Answer:
E. 1,700 is your answer. 
Step-by-step explanation:
What you do is you add 668 + 575 + 453 together. 
668 + 575 + 453 = 1,696.
The hundreds place is the 9. Since the 9 is bigger than 4 it gets rounded up. That means the 6 in front of the 9 becomes a 7 and 9 and 6 become a zero.

Perimeter = 2L + 2W
since it’s a square, all sides are equal so
perimeter = 4s
s = 13
so multiply 13 by 4 
perimeter = 13*4 = 52
