Which unit is used to measure area in the SI system?

• A. Square Yard
• B. Square Meter
• C. Square Foot
• D. Cubic Meter

Answer: (B)

The square meter is the standard unit of area measurement in the International System of Units (SI). It expresses a two-dimensional space and is derived from the meter, which is the base unit of length in the SI system. One square meter is defined as the area of a square with sides that are each one meter long.

This measurement is widely used in various applications, including construction, land measurement, and other fields where area calculations are necessary. The use of square meters allows for a consistent understanding across different regions and standards, making it essential for scientific, commercial, and personal applications.

In contrast, square yards and square feet are units of area measurement used in systems other than SI, specifically the imperial and customary systems. While cubic meter pertains to volume rather than area, it is important to recognize that each of these units serves a specific purpose within its own measurement system.
