I'm sorry, but the solution is still not clear to me. How is the answer A and not C?
We only know that the figure is a rectangle.
We don’t know whether the rectangle is a square or not.
The circle we can draw within a rectangle will be limited by the shorter side (here the circle must stay within the boundaries of the rectangle)
Imagine a circle with diameter 4.
The MAX Area circle we could draw would be perfectly inscribed within a square with equal side lengths of 4.
Now imagine the square is stretched along its length.
We now have a rectangle with width = 4 and the length = 100
Again, the MAX circle we can draw within this rectangle will have a diameter of 4: the same circle as in the case of the square with side length 4.
The circle is a set of equidistant points from the center. Hence, no matter how we tried to draw the circle, we are limited by the shorter side of the rectangle.
Hope that helps a bit? 🙂
