The perimeter of a square is to between 14 and 44 feet, inclusively. Find all possible values for the length of its sides.

Answer 1

7 <= x+y <= 22

So, just start listing

x y
1 6..21
2 5..20
.
.
.
6 1..16

Answer 2

Oops. That is just the integer lengths.

I'm sure you can set down the two inequalities restricting x and y.

Answer 3

square not rectangle I think
14 <= 4 s <= 44
so

3.5 <= s <= 11

Answer 4

duh -- read twice, write once.
