20×10

20×10 is a mathematical expression representing the product of the numbers 20 and 10. The result is 200. The notation uses the multiplication sign ×, a standard symbol for multiplication in mathematics.

In geometry and design, 20×10 commonly describes dimensions, such as width by height or length by width. A rectangle with sides 20 units and 10 units has area 200 square units, and its aspect ratio is 2:1. If the dimensions include units (for example, 20 cm by 10 cm), the area would be 200 square centimeters (200 cm²).

In data structures and linear algebra, 20×10 can describe the size of a two-dimensional array or matrix, with 20 rows and 10 columns, yielding 200 elements in total. In spreadsheet or grid contexts, a 20×10 grid consists of 20 rows and 10 columns of cells.

Because multiplication is commutative, 20×10 equals 10×20, and the order does not affect the product in calculations. The expression is a concise way to convey a two-dimensional size, a grid dimension, or a numeric product, depending on the context.
