luas

Luas is a Malay and Indonesian noun meaning area, extent, or surface. It denotes the measure of a two-dimensional space and is widely used in mathematics, geography, and surveying. The term functions as a general label for the size of a region or object, and it forms common compound terms such as luas tanah (land area), luas wilayah (area of a territory), and luas permukaan (surface area).

In mathematical usage, luas refers to the area of shapes. For example, luas lingkaran means the area of a circle, and luas persegi panjang the area of a rectangle. Units of luas include square meters (meter persegi) and square kilometers (kilometer persegi).

In everyday language, luas helps specify property size in contracts and real estate descriptions, and it is contrasted with dimensions such as panjang (length) and lebar (width). In geometry, luas denotes the two-dimensional measure, while keliling describes a boundary length.
