60×80

60×80 denotes a pair of dimensions expressed as sixty by eighty. In geometry, it describes a rectangle whose sides measure 60 and 80 units. The area is 60×80 = 4,800 square units, and the diagonal length equals sqrt(60^2+80^2) = sqrt(10,000) = 100 units. The ratio of the sides is 60:80, which simplifies to 3:4, a widely used aspect ratio in imaging and design.

Common uses include indicating physical sizes for posters, canvases, or photographs, such as a 60 cm by 80 cm print. In digital contexts it can denote a resolution of 60×80 pixels, which is very low for modern displays. The expression also appears in specifications where a rectangular component or space is described by 60 by 80 in the given unit.

The 60–80–100 relationship reflects a scaled 3–4–5 right triangle, illustrating the consistent Pythagorean triple when the sides are 60 and 80 units. This makes the configuration a straightforward example of how right triangles and rectangular dimensions relate.
