What is a common unit of measurement for area?

Square meters is the standard unit of measurement for area in the International System of Units (SI). It describes a two-dimensional space by providing the product of two lengths measured in meters, essentially allowing you to calculate the surface covered by a shape. This unit is commonly used in various fields such as engineering, construction, and agriculture to quantify land area, floor space, and more.

Other choices present different types of measurements: liters measure volume, grams measure mass, and inches can measure length but are not specifically focused on area without being squared (as in square inches). Hence, square meters stands out as the appropriate measure specifically designated for area.
