Polygon 27 miles2 what is side a

Question

There is a polygon that is 27 miles2 what is side a

Answer 1

Should be "there's a regular polygon that has Area = 27 mi²; what is the length of its side a?

 

Every regular polygon has n sides, and there's a formula--each one different, depending on n.  So the information is insufficient; the word regular is required, and n should be known; then it is possible to solve for a.
