Area is a fundamental concept in geometry that measures the size of a two-dimensional surface. It's the total amount of space contained within a flat shape. In this interactive grid, each square represents one square unit. When you draw a shape, the tool calculates the total number of squares it covers. The area of a rectangle or a square is found using the formula A = l x w, where l is the length and w is the width. A common way to write a square unit is with a small "2" as a superscript, such as cm² or in².
