• 📏 Perimeter Definition: The perimeter is the total distance around the outside of a two-dimensional shape.
• ➕ Formula for a Rectangle: Perimeter = 2 * (length + width), or $P = 2(l + w)$.
• 📐 Formula for a Square: Since all sides are equal, Perimeter = 4 * side, or $P = 4s$.
• 💡 Real-Life Examples: Fences around yards, borders of gardens, frames around pictures.
• ✏️ Units: Always remember to include the units (e.g., cm, m, inches, feet) in your answer.
• 🔑 Problem Solving Tip: Draw a diagram to help visualize the problem!
