📚 Topic Summary
Perimeter is the total distance around the outside of a shape. Imagine you're building a fence around your backyard – the amount of fence you need is the perimeter. Area, on the other hand, is the amount of space inside a shape. Think of it as the amount of carpet you need to cover your bedroom floor. To find the perimeter, you add up the lengths of all the sides. To find the area, you multiply the length and width (for rectangles and squares). Identifying whether a problem is asking for perimeter or area is key to solving it correctly.
