Perimeter & Area
📋 What it is
Perimeter is the distance around; area is the space inside, in square units.
🗣️ Coach says
Perimeter is the walk AROUND the edge (add the sides). Area is the space INSIDE (cover it in unit squares; length × width for a rectangle). They answer different questions — fence vs floor.
🧠 Memory hook
Perimeter = around (the fence). Area = inside (the floor, in little squares).
😂 Giggle
The metric system is the ruler of the world — it really measures up!
😲 Whoa!
Farmers care about both: perimeter decides how much fencing to buy, area decides how many crops fit.
✅ Quick check: A rectangle is 5 m by 3 m. What is its area?
Say your answer out loud first — then reveal.
15 m² — 5 × 3.
Area of a rectangle is length × width, in square units.
🧪 Try it! (2 minutes)
Walk the perimeter of a rug (count steps), then imagine covering it in floor tiles (area).
