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 think first. Chain of thought:
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.
Therefore, the answer is 25.
