Area is the measure of the amount of space inside a two-dimensional shape.
Area is expressed in square units such as cmΒ², mΒ², or inΒ². The area of a shape depends on its dimensions. For example, the area of a rectangle is length Γ width, and the area of a circle is ΟrΒ². The concept of area is fundamental in geometry, construction, land measurement, and many real-world applications where surface coverage matters.
The concept of area dates back to ancient civilizations. The Egyptians used geometric methods to measure land after the annual flooding of the Nile. Greek mathematicians like Euclid formalized area calculations in his work "Elements" around 300 BCE. The method of exhaustion, pioneered by Eudoxus and refined by Archimedes, was an early form of integration used to find areas of curved shapes.
