Solution:
Q1: 2 inches
Q2: 28 inches

The length of one side is 5 in. so the other is also 5 in. That is 10 inches. To get 14 inches the width has to be two inches because 2 and 2 is four. To get the perimeter you add all the sides. To get answer two, I know that 10 plus 10 and 4 plus 4 is 28, so it is twenty eight inches dubbled.
