We know that the perimeter is the all the sides added up together. Generally, you have 
, where l is length and w is width.
For a square, all sides are of the same length, so you can write
, where x is any side.
If the smallest perimeter is 14, then
, so x is 3.5. If the largest perimeter is 72, then 
, so x is 18.
Therefore, you have 3.5 ≤ x ≤ 18.
For a square, all sides are of the same length, so you can write
If the smallest perimeter is 14, then
Therefore, you have 3.5 ≤ x ≤ 18.
to find the hypotenuse (or the ramp in question 4) you can use the equation
with a and b being the 3 feet and 9 feet and c being the unknown (ramp).
So if you plug 3 and 9 into the equation, it looks like this.
then square them.
simplify.
take the square root of both sides.
is approx. 9.5 so the answer would be H.
