Answer:
y + 8
Step-by-step explanation:
Smaller number = y (Given)
Larger number - smaller number = 8
Larger number - y = 8
Larger number = y + 8
Verification:
y + 8 - y = 8
I believe the correct answer is 8sqrt2.
perimeter: 16
multiply it by 4 (since it's a square)
area: 80
it's a square so all you need to do is multiply it by itself
4 x 
16 x 5 (squared them)
80
