Although there is no image shown for this question, Pietro Perigino is an artist that is known for his peculiar depiction of space behind his painting. His works were famous before the arrival of Michelangelo's painting of the Sistine Chapel.
The paintings actually had presented great Linear perspective that redefined the idea of space in the paintings. He played around with a simple technique that adapts well with the foreground, middle ground and background.
For the answer to the question above, let's start with the whole circle.
Let's assume that <span>the maximum possible area of a rectangle inscribed in a complete circle is achieved when the rectangle is a square.
</span>
D= Circle's Diameter = 16
square's area = (D^2) / 2 = 256/2 =128
Imagine we want to break the circle into two semicircles, the square would be divided into two rectangles which would have the maximum possible area.
rectangle's area = square's area / 2 = 128/2 = 64
