If I were to draw 4 quadrants of circle inside a square, with each right angle being the angle between the arms of the quadrants, what will be the area of intersection.
Now I've tried this a few times and there's no way to find the area of the inner squarish figure which occurs twice in the intersection.
Finally, a preemptive apology, I am just a 15-year old who is a semi-Maths enthusiast who is unaware of proper terminologies.
