Question 168231
in the 1st, yes is the answer. try a rectangle that is (1/2)by 13  area is less than 7 and perimeter is quite a bit bigger than 16.

I believe that a square will give the biggest area of a rectangle with any given perimeter, and the area of a square with a perimeter of 16 is 16 so I would say no on the 2nd part.
