The area of the rectangle is 9%2A4=36 .
A square with an area of 36 must have a side length of 6
because 6%2A6=36
(or 6%5E2=36 if you prefer to write it that way).
A square with a side length of 6 for each of its 4 sides has a perimeter of
4%2A6=highlight%2824%29
(or 6%2B6%2B6%2B6=highlight%2824%29 if you prefer to calculate it that way).
