📐 Part 1: Understanding Perimeter

1. What is perimeter?

The area inside a shape

The total distance around a shape

The number of squares inside a shape

2. To find the perimeter of a rectangle, you need to:

Add all four side lengths together

Multiply length by width

Count the squares inside

3. A rectangle has sides of 5cm, 3cm, 5cm, and 3cm. What is its perimeter?

15cm

16cm

8cm

🎨 Part 2: Grid Practice

4. Draw a rectangle that is 4 squares long and 2 squares wide on the grid below. Then colour-code each side with different colours and calculate the perimeter.

My perimeter calculation: _________ + _________ + _________ + _________ = _________ squares

5. Draw a square that is 3 squares on each side. Colour-code the sides and find the perimeter.

Perimeter of my square: _________ squares

6. Look at this rectangle with length 6cm and width 4cm. Calculate its perimeter and show your working.

Answer: _________ cm

🌱 Part 3: Garden Design Challenge

7. Design a rectangular garden bed on the grid below. Your garden must be between 5-8 squares long and 3-5 squares wide. Calculate how much fencing you would need (the perimeter).

My garden dimensions: Length = _________ squares, Width = _________ squares

Fencing needed (perimeter): _________ squares

8. Extension: If each square on your grid represents 1 metre, how many metres of fencing would you actually need for your garden?

9. Explain in your own words how you calculated the perimeter of your garden bed.
