Since all four sides of a square have the same length, the perimeter of a square is just 4 times one of the side lengths. The perimeter of the square and therefore the circumference of the circle is 5.5*4=22. The circumference of a circle is 2 times the radius multiplied by pi. The radius of this circle is therefore:

$\dfrac{22}{2\pi}\approx 3.503$

Since the area of a circle is $\pi r^2$ , the area of this circle is:

$\pi \cdot 3.503^2= 3.14\cdot 12.271\approx 38.47$

Hope this helps!
