These are the following ways to calculate the area based on the number of sides that exist in the shape, as illustrated below in fig. In general, we can say that the area of shapes can be defined as the quantity of paint required to cover the surface with a single coat. Thus, the total surface area is equal to the sum of the areas of all 6 rectangles. For example, a rectangular prism has 6 rectangular bases and lateral faces. The area of the outside surface of a three-dimensional shape or a solid is called Surface Area of that surface. For finding the area of a composite figure that contains more than one shape, we will find the sum of the area of all the shapes forming the composite figure. In reality, not every plane surface can be clearly classified as a rectangle, square or a triangle. To cover the floor with tiles, to cover the wall with paint or wallpaper or to build a swimming pool are other examples, where the area is computed. To determine the size of the carpet to be bought, we often find the area of the room floor. This further led to a derivation of the area as a particular amount of space contained within a set of boundaries. The origin of the word is from ‘area’ in Latin, which translates to a vacant piece of level ground. The area is measured in square units such as square feet, square centimeters, square inches, etc. The area of an object is the number of unit squares that cover the surface of a closed object. In geometry, the area can be defined as the space occupied by the surface of an object or any flat shape.
He also gave the earliest proofs for the volume of the sphere and surface area. However, he was, as far as we know, the first to prove it formally. Archimedes, no doubt, wasn't the first to realize the fact.
Later in 287 BC, the great mathematician Archimedes from Greece discovered the area and the perimeter of the circle and the relationship between spheres. The first recorded use of areas was in ancient Babylon, where they used it to measure the amount of land that was owned by different populations for taxation purposes.
