What is the unit symbol for area?

• A. m
• B. m²
• C. m³
• D. mm

Answer: (B)

The unit symbol for area is represented as m², which stands for square meters. Area is defined as the amount of space enclosed within a boundary, which is calculated by multiplying the length by the width of a surface. Since area involves two dimensions, the unit of measure is squared. Therefore, when measuring area in the metric system, one would use square meters, denoting the dimensions as meters multiplied by meters, resulting in the squared unit designation of m². This clearly signifies that the measurement accounts for both length and width, distinguishing it from units that measure volume or linear dimensions.
