50×60

50×60 is a notation used to describe a rectangle or grid with dimensions of 50 units by 60 units. The multiplication symbol × is read as 'by' when used for dimensions, and as 'times' in arithmetic. If the same unit is used on both sides, the expression can be used to compute area as length times width.

Calculation: 50×60 equals 3,000. This follows from the distributive property: 50×60 = (5×6)×100 = 30×100 = 3,000. In terms of units, a 50 by 60 rectangle has area 3,000 square units. For example, 50 cm by 60 cm yields 3,000 cm², which is 0.3 square meters. If expressed in inches, 50 in by 60 in yields 3,000 in², equal to about 20.83 square feet.

Applications: The expression is commonly used in describing sizes of objects such as posters, frames, tiles, screens, or photograph formats. It also appears in grid contexts, where a 50-by-60 grid comprises 3,000 cells, and in digital imagery, a 50×60 pixel image contains 3,000 pixels.

Alternate meaning: In mathematics beyond geometry, A×B denotes the Cartesian product of sets A and B, which has size |A|×|B|; thus a 50×60 Cartesian product contains 3,000 ordered pairs if A and B have 50 and 60 elements, respectively.
