📝 The Math Breakdown

  • Area (The Inside): Multiply the Width by the Height to find how many square units fit inside.
    Formula: Area = W × H
    Calculation: 6 × 4 = 24
  • Perimeter (The Outside Border): Add all four outer sides together.
    Formula: Perimeter = (2 × W) + (2 × H)
    Calculation: (2 × 6) + (2 × 4) = 20
