The term "25 cm²" refers to an area measurement of 25 square centimeters. This unit is commonly used in various fields, including geometry, architecture, and design, to quantify the size of a two-dimensional space. A square centimeter is defined as the area of a square with each side measuring 1 centimeter in length. To visualize 25 cm², imagine a square where each side is 5 centimeters long. When you multiply the length by the width (5 cm × 5 cm), you get the total area of 25 cm². This measurement can be useful for determining the size of objects, such as a piece of paper or a small tile, in practical applications.
