📚 Topic Summary
Perimeter is the total distance around the outside of a two-dimensional shape. Think of it as building a fence around a garden. Area, on the other hand, is the amount of space a two-dimensional shape covers. Imagine painting the inside of that garden. To avoid mixing them up, always remember perimeter is about the sides, and area is about the space inside.
🧠 Part A: Vocabulary
