Shape Builder: Area & Perimeter

Measure It Out: Learn and Practice Area & Perimeter !

Let's Learn Area & Perimeter!

🟩 Area: Count how many square tiles (blocks) are inside the shape. That's your area!

Formula for rectangle/square:

  • Area = Length × Width

Example: If a rectangle is 4 blocks long and 3 blocks wide, then Area = 4 × 3 = 12 square units.

📏 Perimeter: Walk along the edge of the shape and add all the sides. That’s your perimeter!

Formula for rectangle/square:

  • Perimeter = 2 × (Length + Width)

Example: If a rectangle is 4 blocks long and 3 blocks wide, then Perimeter = 2 × (4 + 3) = 14 units.

🧩 For twisty shapes: Count the green blocks for area. To find perimeter, pretend you're tracing the outside with a crayon—add up those edges!
