Football stadiums are typically shaped in an OVAL, which is a four-letter word. An OVAL shape is a closed curve that is symmetrical about its two axes, with the ends of the curve being rounded. This shape is often used in sports stadiums, such as football stadiums, because it allows for a large number of spectators to be seated in a relatively small area. The OVAL shape also allows for a more efficient use of space, as the field can be placed in the center of the stadium and surrounded by seating.
