🛎️ What is Area?

  • Area measures how much space a flat shape covers.
  • It is measured using square units.

🛎️ Common Units of Area

  • Common units include mm², cm², m², and km².
  • Each unit represents a square (e.g. 1 cm² = 1 cm × 1 cm).

🛎️ Converting Units of Area

  • When converting area, you must square the length conversion.
  • For example, 1 cm = 10 mm, so 1 cm² = (10 mm)² = 100 mm².

🛎️ Using Area Conversions

  • When converting to a smaller area unit (e.g. m² → cm²), multiply.
  • When converting to a larger area unit (e.g. mm² → cm²), divide.
