They are all polygons: two-dimensional shapes, bounded by straight lines.

First AnswerThey were not decorated. The castle was for protection and a courtyard was meant as part of defense. Second AnswerCourtyards have various names depending on the type of building they are in. In castles, a courtyard is referred to as bailey. In a monastery or church it is called the cloisters. In ancient Rome, it was an atrium, or if there was a garden, a peristyle, and the villa rustica of the French nobility of the Early Middle Ages retained this design. For schools and palaces, large square or rectangular courtyards were called quadrangle. Towns and cities had courtyards, which may or may not have been intentionally designed. Simple houses joined together could form a courtyard. Clearly the decoration depended on the use. Some of those such as would be found in palaces or the villas of wealthy people were often paved with expensive decorative stones. The architectural decoration could on ornately carved columns of walkways going around them. They could have trees growing in them or gardens of decorative plants. For special purposes they could be decorated with brightly colored banners and lanterns or torches to brighten them at night.At the other extreme, courtyards could be, well, plain, and probably too dirty and smelly to talk about in an answer on decoration.

The ancient Greeks would live in a house called an 'Oikos' which would be square in shape with a courtyard cut out the middle to get sunlight and stop heat. The courtyard was also for wells and sacrifices in the altar.
A Cube
There are: 10*15 = 150 square meters
They are plane figures bounded by straight lines.
There is no opposite for a quadrangle, a typically square area or courtyard between buildings, as at a school.
A square is a two-dimensional shape that has four sides (a quadrilateral), where all of the sides are of equal length, and all of the corners form 90 degree angles. A square can be described as an equilateral rectangle, or conversely as an equiangular rhombus.An architectural square surrounded by buildings can be called a quadrangle or courtyard.
