"If length of one side of a regular polygon is 25% of its perimeter", then s=0.25P. Divide both sides by 0.25 to get P=s%2F0.25 and simplify to get P=4s. Since this is the formula for the perimeter of a square, this means that the polygon has 4 sides.

Divide 25% of the perimeter into 100% of the perimeter, which is to say divide 1 by 0.25 -- which has the same answer as the question: "How many quarters (25-cent pieces) in one dollar?"
