While practising for his upcoming math exams, Hayes realised that the area of a circle he had just solved was equal to the perimeter of a square he had solved in the previous problem. If the area of the circle was 100, what's the length of one side of the square?
Let's say the side of a square is s.To get the perimeter of a square, you add all the sides, which is s+s+s+s = 100.
Therefore, 4s=

100.
Therefore one side of the square is s =100/4 =

25.
